Item Number – SCP-027 Object Class – Euclid Special Containment Procedures – The host of SCP-027, currently subject 027-02, is to be kept in a 5 meter by 5 meter containment cell with a graded, raised floor connected to a strong vacuum system. All creatures removed from the subject's containment cell are to be incinerated except for a small portion to be diverted for analysis and necropsy. The cell is to be cleaned and inspected for structural damage daily. Subject 027-02 must be monitored by at least two personnel at all times. Any unusual behavior or vital signs on the part of the subject, or the appearance of any unusual species in the subject's vicinity, must be immediately reported to Level 4 personnel. Security personnel assigned to SCP-027 must be inoculated against all known animal-borne pathogens, and must be armed with tranquilizer guns, with standing orders to subdue the subject if the need arises. Until SCP-027 is better understood, no personnel of Level 4 clearance or hire should approach within 200 meters of the subject. Description – SCP-027 appears to be a phenomenon of unknown source that seems to be tied to one human subject, currently 027-02, at a time. As a host to SCP-027, subject 027-02 is constantly surrounded by swarming vermin that are drawn to his location. The subject does not appear to be able to assert control over these creatures in any way, and is in fact prone to occasional attacks from feral specimens. These creatures have also been known to attack personnel who approach too closely. Wherever the subject goes, an initial swarm of flying insects, such as gnats and flies, will start to form a cloud around him, usually within 2-3 minutes. Shortly thereafter, crawling animals including lice, cockroaches, worms, spiders, data expunged, mice, and rats will begin to appear. The longer the subject remains in a location, the more vermin will gather there. When the subject leaves a location, some of these creatures will follow, but most will disperse. SCP-027 has been known to transfer between hosts once, upon the death of the first known host, subject 027-01. Since SCP-027 could likely repeat this feat upon the death of subject 027-02, all high value personnel should be kept far away from the current host, until more about SCP-027 is understood. SCP-027 has also likely transferred between hosts an unknown number of times before containment. Research into potential previous hosts has commenced, with preliminary evidence suggesting that SCP-027 may have existed for at least a few years. It has not yet known how SCP-027 chooses or attracts animals, or even what SCP-027 exactly is. The previous host never expressed having any sort of communication with a separate conscious entity. Analysis of the current host has been inconclusive at best. Appendix 1, Timeline of Significant Events, April 19, 1991. Subject 027-01 is discovered in an abandoned warehouse outside for a while. That had been completely overrun by rats, cockroaches, and other vermin, and is contained and catalogued as SCP-027. The subject is described as a Caucasian male in his late 30s, of average height, but gaunt, filthy, and covered in bites and scratches. The subject also shows symptoms of degraded mental health, evidence of heavy use of alcohol, and illicit drugs, and signs of prolonged sleep deprivation. October 01, 2001. Subject expires. All topsy shows more than 70% of the subject's body data-expunged, a colony of rats nesting in the subject's abdomen for at least a few generations. October 01, 2001. Between 140 and 150 hours after the subject's death, security officer K.F. Reports being awoken by breathing problems due to a large housefly having crawled up his nose, later shown to have laying eggs. Subsequent observations led to categorization of Officer F. Subject 027-02. The original host is reclassified as Subject 027-01, and SCP-027 is redefined. Data expunged. Appendix 2. Transcript of Interview 027-201. The following interview was conducted on October 01, 2001. Shortly after Subject 027-02 was identified and transferred to the containment cell that had housed Subject 027-01, Dr. Jameson. Good morning, Officer F. How are you feeling? Subject 027-02. Scared, confused, mostly scared, though. J. Understandable. S. And itchy.  But what about, um, inside? Do you feel anything different inside you? Like a... S. Thinks and scratches his head. No, I don't think I do. I haven't really noticed anything like that. J. You haven't felt anything different since the original host died besides the itching. S. No, I can't say I have. J. What about any sort of voices or compulsions? S. Agitated. No, I haven't felt anything except bugs crawling all over me. Feel dirty and scared and... Doc, what about my family? You gotta get this thing out of me so I can see them again. J. Of course. Going to do everything we can to get 027 out of you. God, I'm sorry, Cr- Note, shortly after this interview took place, Dr. Jameson and several other members of the research team for SCP-027 were transferred to the SCP-1772 project. Lesson complete. If you missed the previous orientation, go watch SCP-026 after school retention right now. Or for the complete course, watch this playlist.


So, I'm going to talk about paper we wrote recently, it's 3D partition functions in Kivara Sora, which has been written together with Antoni Delin, who is doing his first post-doc in Milano, and with Fabrice Nyeri, who is doing his post-doc in Uppsala. So please, you know, unfortunately, I have to leave tomorrow to US, but please feel free to ask the many complicated questions and, you know, don't ask me, okay? Good. So let me try to give you idea first, and then I will try to give more pedagogical talk because the subject is rather technical, so I will only outline the some technicalities, but I will concentrate on the idea, but the thing is the following. So, thank you. The idea is the following, that in principle, typically, when we discuss, so we do localization, so for example, we discuss partition function for S3, I don't know, for land spaces, etc. So for simplicity, I concentrate on 3D partition functions, and maybe toward the end, I will make some comments about 5D. So we calculate these partition functions, and typically, you know, there are functions of very few variables. So there may be functions to be of, I don't know, of a rank of gauge group, maybe level, maybe some kaoplan, phalaeolopoulos term, but it's a finite. So in a way, to a large extent, it's a number and, you know, it's a bit boring number, so it's a bit boring to study. Of course, some people concentrate on this number quite a lot. There is typically some matrix representation, and this guy depends from very few parameters. At the same time, it's not the only quantity we can calculate localization, we can also calculate typically some set of wilson loops in some, you know, representation. So in matrix model, it corresponds to certain insertion, so in a while, I will make it very precise. But typically, in all discussions, we talk about either partition function, or we talk about wilson loops, etc., but what does make sense, it makes sense to put, to take these two objects together and put them into the generating function. So eventually, my d13 now will depends, of course, on some finite number of parameters, which is related to the theory, but then typically it will depend on infinity many guys, which people typically call times. It can maybe one set of times, it may be two set of times, etc. And then the claim is the following. That's what I will try to explain, that these guys, in terms of these infinity many constraints, satisfy infinity many, many PDEs, very complicated PDEs, but these PDEs, they have very clear geometric algebraic structure, and they're related to quiverasaur. So this is idea, and this is, this is general pattern in all other dimensions. Again, in some dimensions, people just didn't study, but, you know, for example, in 5D, necrosis partition function, it was a result by Pastein from December 15, you can do the same thing, and it will satisfy infinity many algebraic PDEs. So in a way, the idea is better not to study this or this object separately, put them together, and then you write this. So that's what I will explain, and the basically idea would be that this object has very clear interpretation in terms of CFT, and this is BPSCFT correspondence. Okay, so before I go there, I assume that you guys don't know much, so I will just outline your idea of what's quiverasaur constraints, and then tell you some basic stuff about quiverasaur constraints, etc. So typically all these guys are matrix integrals with different measure. So when I'm giving you integral, typically, right, so if I write for you the integral, so I have to calculate the number. Okay, this is very cool, you know, you sit down, you calculate it by some means, and typically for this integral, what people typically write, there is word identities, which is basically an insertion of derivative under the integral. Again, it's a true statement, but it's a useless statement, because you cannot really calculate anything. So typically, this is the whole idea here, that instead of calculating this integral, or calculating many integrals, you can basically try to reduce the problem to generate a function. So namely, for example, I can, again, I'm here very few mathematicians, because they ask me a lot about converging, so let's ignore these issues, but I can basically park infinity many integrals in the following object. Let's say t1, t2, etc., and I will write something like this, minus 1 over 2g, x square plus n from 1 to infinity t and xn dx. So in principle, if this is a reasonable function and there is not much analytical thing, so what I can basically translate this purely analytical problem to this calculating this. Then, of course, the question, how do I understand this integral, but typically the most natural thing to say that this is just gaussian weight, and then these guys expand formula, and you know, I can do the formula and write everything explicitly. So then there are two ways, I mean, for this, this is a very nice example. It's good for students to do, but you can basically do this thing in two ways. So one way you can actually sit down and calculate this integral, for example, it's, you know, the only thing to calculate this, you need to know x and power 2p gaussian, what is equal, and then you expand equally, but you can do something else. So you can trade this guys for, you can write infinity many PDEs. So one of the things which I can try to insert, there it's a fallen operator. So as you can recognize, it's almost verisorra, but the thing inside put this guy up inside. So of course, this guy will satisfy the classical verisorra. Then you take this guy, you put inside, and then you get, of course, identity, very trivial identity, e minus one over two g x square plus. So if you have questions, please feel free to interrupt me. Let me put k here. And this is dx equal to zero. Well, now what you do, you just simply differentiate with respect to x, everything, and then whatever extra terms you have, you can generate them by taking tk derivatives. And then what you eventually get, if you, yeah, are you a mathematician? Then why do you ask?  It depends how you understand this integral. I'm told you how the way you understand this integral. So you treat g as actually positive guys. So this is Gaussian weight, and these guys, you just expand formula. For example, this is one way of understanding integral. Yes. Yes. No, I'm not there. This is, I mean, this is that level. I mean, we come to three manifold. Nothing to do with this. I'm trying to explain your idea. So typically, you know, the idea is in a way trivial. But, you know, as you just make this idea algebraically more and more complicated becomes, you know, much more meaningful. But the idea is very trivial in a way. So instead of calculating integral, so I have integral, I have word identities. This is empty statement. Now what I'm doing is I'm writing for, instead of integral, I'm generating function for all integrals. Let's forget convergence. Let's forget all this nasty mathematical questions. Let's believe everything works. Okay.  So for example, if I assume that n more than equal to minus one, then this guy is equal to zero. Now what I'm telling you that I can do this exercise, I can actually differentiate on the integral. I can write, I will have only powers here of x. And then eventually what I will get out of this, if you want it to be concrete, I will get some differential operators, ln written in t's and derivative of t's acting on zeta of t equal to zero.  Again, this is extremely trivial exercise, but in a way, so n plus one factorial t, tn minus g, n plus two factorial dt, n plus two plus, sorry, I forgot here, I just decided for convenience because put here k factorial. Again, it's not of course important, so n plus s factorial and then s minus one factorial ts, s plus seven, something like this. And then you can write, let me not write it, you can write the same for l one, three operator, l minus one operator. So what I'm telling you is the following, that this generating function of infinity many variables just killed by this first order differential operators. And you have, and of course next thing you can just check that these differential operators of course satisfy exactly the same algebra. So you can check that these operators satisfy the same algebra. Now what you can do, again, the thing is why do you do it? Because as I told you, either you try to solve this PDE so you can actually calculate integrals and model some analytical details what you can get, you can just get this thing. So this is generating function for integrals in one variable. So this is called Bell polynomials related to Schurke polynomials. So the whole thing is a following, you take this integral, either you calculate it, in this case you can calculate it, or you can prove, you can try to derive the value of this integral from verisoroconstraints. Again, there is obviously verisoroc constraints do not feel fixed normalizations because this is PDE, I mean this does not fix the constant value of the integral. But this is idea of verisoroconstraints just in very simple example. Any questions? So the next level of complication, this is our favorite standard Hermitian matrix model. So Hermitian matrix model is the following, again, this is like 25 years old stuff, but so what I can do for you, I can write for the following model. Again, I'm introducing, so I will do the integral over u n le algebra, so it's a vector space of, so this is a space of Hermitian matrices. So I'm writing the back measure here, and then I'm writing here minus sum over s 0 to infinity t s trace of m s. Again, if you're worried about convergence, you can put Gaussian factor, I mean you can sort of make things so you can in principle try to look at the algebraic things. So what is obvious is that, I mean, the Gaussian measure over le algebra will be invariant on that joint action. So if I send my mu to u dagger mu u and u now is in u n, so this is invariant. So there is very standard exercise that you can just translate this integral to something like this. So this is, again, my infinite times, and then I will have here a product over r n. So by any Hermitian matrix, by unitary matrix can be diagonalized. So I can basically diagonalize this measure, the only thing I have to keep a track of things like Jacobi, etc. So I will have d n lambda, and then here I will have i minus j lambda i minus lambda j square, and then here I will have s from 0 to infinity t s, and then I replace here i from 1 to n lambda i s. Then again here what you can do in this simple integral, you can try to repeat exactly the same game, and that's what people did. So it was one of the speakers who refused to come. I did the Russian one, so Morozov and Mironov, I mean, they did this version of the trick, but you can take this object, so you would like to calculate, and one of the things you will insert here is operator l n, which would be minus sum i from 1 to n d d lambda i lambda i n plus 1. So obviously this is just classical verisor, so I have n variables, I just look at the sum of these guys, so you can easily, well there is nothing to check, you know that l n l m n minus m l n plus n. So this is classical verisor. Okay now I'm not going to repeat the thing, but I want to basically bring you the message. So this guy, this is matrix integral, it has nothing to do with conformal field theory. But then what you do, you do the following exercise, and that's what Mironov is Morozov did in 9091. So in principle you can put this operator here, you can actually differentiate, you will get some terms, you use some, you know, simple combinatorial identities, and eventually you will get that l n on zeta t is equal to zero. Any questions? Okay, and then, so you do this exercise, and then you write this operators. So let me write for you this operators very explicitly. So now this is not first order operators, this is second order. So there will be tk dtk plus second derivative over t0.  So this is the second term, etc. So this is come just from word identities for this matrix integral. So typically you put these guys, it's very obvious why you put here this condition for this powers n more than equal minus one because you don't want to mess up this convergence, for example. So now if you stir for these guys, whoever did a free boson and stir for these guys for a while, then you would realize the following thing. You basically will realize that what you have there, it's a free boson representation. So if I look at my Heisenberg algebra, Heisenberg, and I can for Heisenberg algebra, I can pick up some representation and the most obvious representation to pick up again in my discussions, I'm a bit ignoring zero modes, etc. So basically what I can do, I can choose these guys to be something like square root of n tn. So introduce infinity many variables. So this is my creator operators. So my n is positive. I'm sorry to confuse you, but this n has nothing to do with that. Okay. And then my creator operators, this is guys which would be just proportional to derivative, something like this. So this is representation of Heisenberg. Now if you pick up this representation up to some numeric, stir at this formulas, what you realize is the following that this is nothing else. So what you have there, it's the following formula. It's one over two m from minus infinity to infinity normal ordering of a m minus m a m. So basically this is free boson. Again, at the time, it was not that obvious. So this, I mean, this integral, you take an integral, you know, just integral over the algebra, and eventually this integral, the rest of the constraints related to free boson. So if you now try to think a bit more what you have. So this is what I'm telling you, this is pretty standard thing. I'm just, I will do it more and more complicated in a while. Okay. So basically one of the way of looking at this integral is the following. So I introduce my free boson. And then basically I would like to construct some guy so I can think about these guys as an element in a Fox space. For example, I pick up this representation. So for example, you know, I can construct all my states, polynomials, etc. So all this, you know, theory of symmetric functions, I mean, can be recasted. I mean, it's related to representation of Heisenberg. So it's this Fox space. And then I basically have to construct for your state, which would be annihilated by these guys, etc. So in a way, this problem already, it's related in somehow to single vector fields. But the very canonical way of doing it is the following. I basically can introduce for you a screening current, which up to the fire of lambda. And the thing is that these guys with these guys behave in very concrete ways. So it's typically ln is s of lambda. This is some derivative of some operator. So it means that if I integrate this guy, so if I do integral of a correct contour, so that derivative vanish, then this is zero. So this is typically called screening. So this is current, this is screening charge. And then what you can think about zeta t. So zeta t for Hermitian matrix model can be thought as a following, that you just take your object, which let me denote. This is let me denote q. So I just take a qn and act on the vacuum. So in this representation, the vacuum is just identity. And of course, this is by definition will satisfy verisorra constraints, because verisorra hitting this, they commute, they hit the vacuum, then annihilated, this is zero. And in a way, the matrix model, if you will just try this integral of this, you have to do the normal ordering. And exactly when you will do the normal ordering of these guys, sorry, we're here, right. Yes exactly. I mean, it's a representation, right? So what I'm saying to you, for you, for example, it's obvious that I can, you know, what I'm saying is the following that I can write for you a minus one, a minus two, this is the same as a polynomial t1, t2, right? That's that's a sort of statement. It's a representation. It's true in a concrete representation I choose for Heisenberg. Okay. So this is in a way one of the way of looking at Hermitian matrix model. And the thing is that whatever matrix model we get, you just have to modify the story somehow to make it more exotic. But this is the idea of verisorra constraints. Any questions? Just find final comment is that when you order these guys, so when you do normal ordering, what you will get, you will get exponent of a sum i not equal to j log of lambda i minus lambda j. This is standard calculation in the CFT, which is of course the same as a wonder month. Okay, I mean, right now, when I the way I'm presenting it, it's very obvious 25 years ago, it was not obvious. So now what you can do, so our goal is the following that our goal eventually to reproduce some measure. So this is where is canonical simple measure. In, for example, in localization, we have more and more complicated measures. So the idea, I will first explain one basic example, and then I will spend time explaining the main result of the paper. But one of the things is the following that we'd like here to get a different function, something more complicated. And one of the way of doing this is basically try to deform verisorra. So we'll look at different deformations of verisorra. So let me write this down explicitly. So I will now start to talk about q verisorra or I'm not going to give you any general theory. I'm just mainly concentrated on a free field realization, free realization. But the whole idea we keep this philosophy from Hermitian matrix model, but we deform Heisenberg, we deform guys, we deform these guys so they become not quadratic, they become something complicated, but they still satisfy some algebra and then you get eventually the same thing. So these things still be true and you will get something annihilated by this operator. So let me talk about Heisenberg. So now I will deform it by some complex numbers, which I will tell you in a moment. Let me pick you and just this is the remote. And then so in general q and t can be complex numbers and there are the following relations. So it depends which numbers you discuss more fundamental. So p is equal q, t minus 1, and quite often you say that t is equal in power q beta. So either I pick up q beta or I pick up qt or I pick up qp, this is just standard things. Again, the whole idea is now, if I try to for my guy like this, so just think if I take this formula and I deform my Heisenberg and start to calculate something like this, again there may be some, I mean modifications, but roughly speaking, I automatically will not get this measure. It will be more complicated. So let me tell you about free-filterization of q-verasaur and what's how it's related to the verasaur. This is just zero-modes. It's a momentum q, so I have to have a zero. So the formula which I wrote here, this is for n and m in integers minus zero. So typically we have to keep a zero-mode. So for zero-modes, we have separate guys. This is some technicality, if you wish. So now, q-verasaur. So this I just take, I postulate and then what I can do, I can do to write for you the following. So what's a q-verasaur? So this is basically a deforming verasaur, not within Lie algebras, but within associative algebras. So this has been done around 95, a group of Japanese, a lot at all. So let me write the thing and tell you in what sense it's a verasaur or deformation of the verasaur. So you can write this algebras, so I fairly some structure constant, so they come from expansion of concrete functions. But the thing is that you can fix this function by associativity. So this is fixed by associativity. And then if you now take your q and try to say e h bar and try to expand this in a up to quadratic order, then you can see that sort of only, so if I write for you the formula, t n, it will be two, some constant term plus h bar square beta ln plus q beta square over 4 delta n 0 plus terms of order h 4. So q beta is just some variation. So what I'm telling you is the following that you can write this algebras on that, you can fix it by associativity. But another requirement is that you would like in quadratic order in h bar, these guys will be actual verasaur. So this is called verasaur. So you deform verasaur within associative algebras. This is basically a w algebra. So of course you can ask the following question how to write these guys. So you can write concrete answers for these things. And so this is l plus of zeta plus l minus of zeta.  So this is free field realization. So again it's a computation which has been done by Avat at all, that if you take this Heisenberg, you know, you write these guys, you take these guys, of course you expand them over sum over tn zeta minus n. You can see that tn satisfies this relation. Of course this relation can be written in many different forms. And I'm not writing for you but this is a coefficient of expansion of very concrete function. Okay it's a quverasaur. Then next thing you can mimic in Hermitian matrix model, you can write also the analog of a screening current. So screen current is given by the following formula. So just one comment for you right away that you realize. If I want to now look at these guys as a differential operator, so all this Heisenberg is deformed, I still have a canonical representation of Heisenberg. I mean in a way it depends on your test. I may say that I'm not deforming Heisenberg, I can put all these coefficients inside of this a n and then my complication will pop up here. So I mean it's a folk space, it's the same folk space, I just have an action of totally different object there. But you saw just up to these factors which you can put in definition, I can still write a n for positive n as a derivative in t and this is just a multiplying with negative n as a multiplying t. So now if you look now at these guys and you put here your operator, so you put your representation in derivatives etc, you can see that the operator is horrible, but of course it's well defined, but in principle it's exponent of differential operator. So these guys in the representation of Heisenberg it's up only quadratic guys. This becomes now a very complicated operator but it's totally well defined, there is ordering problems solved etc. So now I'm writing for your screen in charge, so again it's some expression and here e, so beta q, w, beta. The whole thing is done because I would like to mimic exactly what I had before. So if you do the calculation then the thing is that t and this sw is equal to, now it's a difference operator. So I'm not specifying this so this is always a sum operator, but this is almost, it's a q derivative. So you can calculate this so we don't care. Important thing that if I take a correct counter, sorry w, so if I take a correct counter, so what is very obvious is the following that if I take a correct counter for integration then of course this is zero. Simply in this integral I can change instead of q w, I multiply here, I change variables in this integral, nothing so this is the same integrals. Again the thing is that you have to think about the counter but let's say we take a counter which is, so it means that if I integrate these guys, so if I integrate these guys of appropriate counter then I will get that this is equal to zero. So from this point of view I can repeat exactly the same game I did before. There is some subtlety zero modes etc. I'm not going to discuss them but now what I'm telling you that I can take my integrals roughly speaking so in power n put on the vacuum and get something, okay? So I get something and then I'm saying that this something, if I call it zeta, so this something you'll be annihilated automatically by this positive. So let's ask what this is so you can actually calculate. So this is, I'm going to write for you the thing explicitly. So my zeta of t looks as follows and that's when three manifolds and gauge theory will enter in a moment. So this is just some complicated but straightforward calculation. So what I have, I have some counter integral of our origin. i from 1 to n dwi 2pi iwi then I have here and from zero to infinity, okay? Let me write this in these notations and then w, so i not equal to j wi divided by wj q infinity and then here I will have my t k k right from one to infinity i from one to n wi k. So how do you get this integral? What you do, you write your screening charges. So this comes from the measure. So this guy is identified exactly with my screening charges in power n acting on the vacuum. So this comes from normal ordering and this is just my generating function. This is creator operators in my conventions. So you still have them there. So I mean these guys still act on the vacuum. I mean this is a generating function and this comes from normal ordering. So is everything clear? The symbols are all just clear. Do I have to define them? Boyd, I understand what's written here, right? Let's assume so. Okay, good. But now the thing is that when you stare at these guys what you realize is the following that this is in fact a partition function for un theory for n equal to un theory plus a joint chiral vis mass on the following geometry. So t, so it's a disk which is you currently rotate. So it's a two disk time circle and the parameter t it's roughly exponent of the mass. So this is a, so in a way what one can say right away then if you know again it's identification. But the statement is the following. If I would turn things around, if I will put Wilson loops along s1 circle and put them all in generating functions here, then I will get a sum object which would satisfy infinity many constraints. So there's a lot of relation to McDonough polynomials. I'm not discussing it here. Okay, what is important here is identification of this object with this object. Again when I'm saying partition function I might actually mean a generating function. Okay, so now let me explain the main result here and that's what I'm doing. So I'm interested in a compact manifold. Let me start with s3. So for s3 if I take the theory, so I'm taking n equal to u n theory plus a joint chiral mass m. So it's generalizable to marginal theories. I'm just looking at simple examples. So my partition function would look as follows. It's irm and I will have a dnx and then I will have here i not equal to j. Then there is this double sign. So my s is squashed. So what I'm thinking about my guy is omega1 zeta1 square plus omega2 sorry omega2 zeta2 square equal to 1. So xi minus xj w1 w2. Then there is s2m plus xi minus xj omega1 of omega2. And then typically here, so let me be more pedantic. I tried for you explicitly. Yep, nothing special. The thing is you do what you can do. So this is a thing. I mean I'm going to, so unfortunately you know there is, if you want to go to concrete things, just let me make comments. So the results were explicitly has been calculated. There is closed form. It's s3. It's a land space. It's s2 times s1. So this is on the market exist concrete formulas and you can take them. And the statement is that I will tell you that all this generating function will be killed by two copies of commuting where there are sort of constraints with appropriate way of identifying parameters. Now what is up to the catch, and this is for any postdoc, speechy students, or even senior staff, I mean n equal to theorists exist on cypher. So it's a result by Fistucci, Demetrescu, and others. So you can put n equal to on cypher. But there are no formulas here explicit. Because one thing that you have a supersymmetry, another thing is to calculate a matrix integral, take into account all flat connections. So in principle we would believe that we should be able to do something here, but you know nobody. So s3 is because people calculate it. We can sit down, there is concrete formulas and do it. But in principle, I mean this is up to catch. I mean one should be able to produce formulas for cypher up to some orbit fold. I mean it's locally free you on action. Absolutely. So this is huge class of manifolds and people prove that there is n equal to supersymmetry, but nobody dared to write the concrete matrix integrals, well maybe exception simons, but again there is a lot of issues here, etc. So no, they're much better than Roushitihin to write. So this is all the story secretly related to complex gen simons. So this is, I mean this is some upgrade, but again this type of theory is not yet well defined. It's under discussion, but secretly it's related to complex gen simons. Absolutely, yeah. So I don't want to discuss this subject because it's outside of my scope, but secretly sort of adding the mass, you know, having UN, this is somehow should be identified with the complex gen simons, etc. There is this discussion in the literature, but it's not very conclusive. I mean there is no clear cut answer. So is that equal to, absolutely, yeah, it's specified. So the rank of this guy tells me how many integrals I have. So then if I take another, you know, theory than I have, so this is like this and then what I wanted to write I still have at least to have time to explain your result, but and here of course what you will have, for example, you will have standard these terms minus i pi k2 of omega 1 omega 2 xi square plus 2 pi i k1 omega 1 over omega 2 xj. So this is, this guy's gen simons level, this is Phylaelopoulos, for example. So now what we want to do with you, we would like to put Wilson loops, but we have to think how to put Wilson loops because we would like to put supersymmetric Wilson loops. So it's important in this logic that I'm choosing my omegas to be generic. So there is, will be lot of algebraic degeneration when they're rational, et cetera, et cetera. So I choose them generic. If I choose them generic, there is only two supersymmetric Wilson loops I can put. One Wilson loops when zeta 1 equal to 0 and it will have this periodicity and another Wilson loop here, it will have this periodicity. What I'm saying is it's not true if omegas are rational. I can have torus nodes for example, but if I choose them generic then that's what I will have. And then it means that, for example, if I want to put a Wilson loop then I have to insert in the integral correspondently the following guys. So I have to insert, for example, trace in some representation of my exponent of 2 pi i x over omega 2, for example. No, no, well it's basically if I think about, you know, s3, s1 vibration, it's only two loops which sits over north and south polo s2, right? So this is, this is the only thing. But this is what supersymmetry is telling me. So either I put this guy or I put another guy and I would like to write the generating functions for both of them. So either I put these guys or I put, so this is representation one, I could equally put in another representation 2 pi i x over omega 2. And of course these guys is nothing as a sure polynomials in, depending from the exponent R1, R2. So if I want to get a Wilson loop, I just put a short polynomial here. And then there is this standard formals which I'm going to use it. If I have a sum of all source, let me call them s, I think this is more canonical. So, so if I write this at t hat s Rw, this is equal to exponent of n more than 1 t n j w j n. While this t n's are related by formal change of t k hat n over n. So that's what I'm doing. Now what I would like for you to introduce a generating function. So my generating function will depend on two set of times t and t prime. So how I define this? I define this as a sum over two set of representations. And then I will have s of R1 of t hat s of R2 t hat prime. And then I will have my integral, which I had before, this insertion of, so I will have d and x. I will have my measure. So this guy is exactly this measure constructed out of double signs. Then I have my key exponent. Okay. And then I have correspond to the Wilson loop R1 e 2 pi i x of omega 1. And then I have s of R. So I would like to have a generating function for all Wilson loops, supersymmetric Wilson loops. So if I do it and I use this formula, then eventually what I will get, I will get the following integral. So my measure, my e w x j. And then here I will have correspondently exponents of n more than 0 t n. And then I will have j from 1 to n e 2 pi i x j over omega 1. And then I have t n prime now j from 1 to n e 2 pi i x over omega 2. So I have to have two times if I want to have keep track of all Wilson loops. So this is my object. So let me now tell you the answer, the main result of this object. So let me for simplicity choose my Chen-Simon's level equal to 0. It just for simplicity result looks simpler. So in principle one can generalize it appropriately. So now I told you that I can write for you this operator, as I wrote before in some representations for t and t, t prime. So I will have to free-field realization for Queue-Verasaur. I'm now looking that this guys is more than equals 0. So these guys by construction are commuting, because this is used different times. The statement is the following that these two guys, t n will kill this function. So this is a priority. Let me also put here prime. This is different operator. So again, I'm repeating that this guy, there is no really obviously symmetry, because this enters with this periodicity, this enters with another periodicity. Now it is important that this is not identical algebras. I mean they have a different parameters. So let me write for you the parameters. So if I'm writing for you the things, so I have two copies. I have this copy one and copy two of my Verasaur. And in gauge theory, I have the following parameters. I have my squashing parameter for the sphere. I have a mass, et cetera. So then correspondingly, copy one, this q1 will be the following. It's a e2 pi i omega of omega one. So omega is just omega one plus omega two. And t is equal t1 is equal to q1 and power b, and it's equal to 2 pi 2 pi i capital M of omega one. And then q2 is equal to 2 pi i omega of omega two. t2 is equal to q2 beta 2 pi i M over omega two. So this is your glutuk Verasaur, and this is the following relation of guys. Again, I'm repeating what is quite unique here. This is just one integral. It's not two integrals. I mean the statement will be obvious if there will be two integrals. So if I took my result from before, when I got Verasaur, then it will be... The thing is, here the trig works because these parameters are gluten very, very particular way. So if you start to think geometrically, so if you think that q1 is equal to 2 pi i tau, so tau is just here. It's a ratio of omega over omega one. Then my q2 is just equal to the following things. It's a minus 2 pi i tau, tau one minus tau. So this is some element of S l to zeta. And this is exactly element which you will use when you will glue S3 out of solitory. For example, if I will... I mean the same statement will be true. The measures will be different. The integral is different. But the same things, for example, true for land spaces. For land spaces you will put here r, etc. Now, what is important, the trick that these two commuting guys lives together nicely, it doesn't work. So I cannot really take two results and reduce two integrals to one integral, etc. So the whole trick, it works nicely only when the parameters of Verasaur, of Toki-Verasaur glued by S l to zeta. Otherwise it doesn't work. So I have no time to explain for you the details, but this is the idea. So this is the main result. And of course, I skipped for you a lot of technicalities. And what I would like to stress at the moment that it may appear trivial result, but it's not trivial result. And the thing is because of screening charges. So when you prove it, of course you will start to prove it by basically by gluing two free bosons and thinking that if I take one free filterization, I take another free filterization, everything works. So I can basically repeat for your story. I can take Tn. I will write for your screen in charge one. I will take another Tn prime. I will write the screen in charge two. And then somehow what is obviously that you would like, for example, now to construct S1 tensor S2. But don't forget they would depend from the same guy. So when I will act this by Tn, so of course Tn will act on this. So I will get D of S1. So this is my Q difference operator. Q difference operator, tensor S2. On S2 it does not act. I will use totally different free bosons for representation of this guy. But the thing is this is not good because I cannot put under the integral because this is not equal to D on S1 times S2.  Well it worked but I cannot put this under the one integral. Of course if I will have here X here Y and integrate then there is no problem. It's really a copy. But I would like to do one integral. And because of this property it's not good. But the magic is the following that if the parameters of this theory are adjusted in such a way that this D acts trivially here then this becomes true. And this exactly happens when it will be glued by SL2Z transformations. Okay. So I have to finish but let me just say a few things. So it can be generalized to these cases LR and some two versions of S2 times S1. Why we don't do other manifolds because there are no explicit formulas for this. So for example we can maybe come up with some ways of gluing currents etc. But we have no measure to compare. So it's simply there are no gauge theory results. So this is one comment. Second comment you can generalize everything. So in fact the theories which one can do one does not have to do yarn theories. If the theories which is extensively considered it's there are 3D cousins considered by Peston, by Nekrasov. It's this quiver type theories. So in principle you can have a UN node and then you have a mantra. The only thing we always have to decorate our UN theory by some adjoint to have an and this is responsible for T parameter. In principle you can go to the limit when T goes to 1. So there is rounds here. A lot of things that will correspond to certain degenerations of the algebra. Some of them studied some of them not studied. So for example one can generalize this to ABG model. The only thing is if you would like to see full algebraic structure you have to take two nodes. So you will have these guys by fundamentals but they also have to decorate by adjoint. If I don't want this adjoint there is certain value of m which I can do it. But in principle so they will be this diagram quiver diagram. So Paeston constructed for this diagram the w-algebra. So there will be these two copies. So if I construct this default ABGM for general values for scores here some partition function generating function will be annihilated by two commuting copies of this quiver w-algebra which was constructed by Paeston. Et cetera for all the theories it works. It's first generalization. Second generalization of course everything all the theories can go onto all these three type of manifolds. You can include of course chance simons level which corresponds to insertion of some vertex operators. So the rest of our constraint becomes a bit more complicated. Okay so I have to finish but basically what we see now here in details is some remains of 5D picture. So in principle the screening charges which I wrote it's the same screening charges which were used by Paeston in his December paper. So in principle one can write a 5D necrosis partition function for this quiver type theories roughly speaking as ejection integrals. So this is symbolic things as ejection integrals. Of infinity many copies acting on the vacuum. So that's a Paeston result. So this is a representation. The thing is that in principle what you do now you talk about generating functions and it will be annihilated by infinity many constraints. So of course this is an R4 times S1. So this is the result of the Paeston December 1050. So for example one would expect here that you can glue so similar things we sort of it's under consideration. We don't know but one can also I mean for the compact manifolds you will glue things there also. The only thing that apparently if you think for a while the correct notion of modular double for quiverasora it should not involve notosal to zeta. It should involve S3 zeta. And the thing is because quiverasora automatically has a symmetry over Q and T. So it means if you take this picture and you impose symmetry about QT you have to generate full S3 zeta. And that's exactly how you're on general five manifolds you glue partition functions etc. But again it's something very speculative and remains to be understood etc. But for example the result which is sort of obvious for Paeston that a partition function on S5 for generating function will be annihilated by three commuting copies of quiverasora with the parameters which you can read from geometry. So I have to stop here. Thank you very much.


and welcome to Lady Aida. Hey everybody, and welcome to a desk of Lady Aida. It's me, Lady Aida, here at my desk. Doing some camera engineering, but first up, Mr. Lady Aida's are gonna do news or updates so you won't tell people. Nothing I wanna talk about. Okay, great. All right, so I'm working on camera stuff. You go to the overhead. I'll show off some of the cameras. So here is- I don't wanna focus on it. I don't wanna focus on it. This is the camera that I worked in on last week. This is one with the lens. And I showed off that I also had these samples that had a motor coil inside of them. We took this apart to show the coil inside. And then this has an autofocus capability, whereas this one, you literally turn this little knob thing to focus it. And I wanna try to get the autofocus working because I thought it was kinda neat, but also I was kind of annoyed like the breakout board that I was using, which is, hold on, I have it here somewhere. Maybe not. But it was basically like this. Didn't work with the autofocus. And of course this is an open source so it's like there's a schematic, but schematic wasn't really clear and like the pin numbering was wrong. But basically it looked like something was shorted. Something, you know, the pin for the motor was bridged on the camera breakout. But luckily I had actually been working on a camera breakout myself because there's a couple of things that I don't like about the standard to buy whatever, 12 pin, eight pin camera boards that people sell. So I designed a simple breakout and I was like, well, this is a good excuse to get it together. So I put two together. And you know, because the final two pins on the camera are that coil, and I think like every other breakout like assumes like, oh, if it's not connected we should just connect it to ground, which is, you know, it's like, it's always at the conundrum like you have a schematic and it says NC and you're like, well, should I actually leave it NC or should I connect it to ground? In this case, you know, most cameras can't get to ground but I kept them floating. And so it was possible for me to red wire, connect this little wire here, which is the motor power to three volts. I just made a little jumper pin on this camera breakout. And so I got the, so then I was able to use the example code from the app note to do auto focusing because you basically have to connect the motor power and then you have to load firmware onto the, there's a little basically a micro controller inside of your DSP chip and you load autofocus firmware on it because autofocus isn't built in. Why? I mean, whatever it's kind of an add-on. It's an extra, maybe by default it wasn't included or maybe you want to put different algorithms in for how autofocus works. Either way, you know, I found firmware around on the internet. It is a binary blob, but you basically, it's 4K kilobytes long. You slowly feed it into iSquared C and then you can request an autofocus command over iSquared C from the camera sensor and it'll do that little like, you know, attempt to like focus in and out until it's no longer blurry. So in the computer, this is the, can you give it a try? Oh yeah, sure. On the computer, this is the Python code. So there's a file that, you know, called autofocus.bin and it's just like binary. There's no, you know, there's no idea what it is. It's just some firmware format. And in the code, you init the firmware by opening the file and you load all that code into address 0x80, like one byte at a time over iSquared C. Slow, but it's effective. Although I might try, you know, I wonder if you can write 32 bytes at a time or more bytes at a time, because that would be, of course, preferable than writing like one address at a time. And then you can read the status at address 3029. And then there's commands to clear the autofocus and reset it. And that's actually, oops, that's actually from the app note. There's an app note called, you know, the embedded autofocus solution. And they say once you load the firmware, you know, here's how you can trigger autofocus mode and here's how you can request autofocus status. So it's actually quite simple. It's like the hardest part is just, you have to make sure like you've downloaded the firmware properly. But all this is closed source and you have to make some open source software to get it to do all this. Yeah, I mean, like the firmware that runs on the camera, I mean, it's like, I don't even know what it is, right? It's just a binary blob and they'll never get to release it and so you can't design your own firmware. But that's, you know, that's not that unusual and I don't feel like that's a reason not to use it. You know, cameras, normally the binary blob would just be built into the chip and you wouldn't even have access to it. So, I didn't remember. Yeah, these are one of those things like we're coming out with an open source camera, but there's always like weird guts inside of a camera just like there's BIOS on a computer. It's always something that we can't get everything, but we'll be able to have open source software for you to interact with this firmware blob, right? That's the... Yeah, I mean, you can still use the camera. I mean, again, like normally, like I was actually expecting that the autofocus firmware would already be loaded in and then you would still just send the commands. It's like they just, I think they just want to make it so you can try different for more blobs. But like, yeah, if somebody ever figures out what chip is inside here, you could probably work and hear it. Do you compile the binary? Let us know. Yeah. Yeah. Okay. So given that, so this is... Besides you use Windows. So you'll never be open source, Lady Aida. Yeah, it's true. You have, you know, there's closed source firmware on the way up to your desk. Yeah. At work. Yeah. So you will never be open source. Well, the camera you're using to film this is also close as my eyes. Yeah. So when you autofocus in it, you know, here I load that firmware file in and it's it.  And of course you can, you could ask for status. So here I've got, you know, in my main loop, this is a main loop that reads, that captures a bitmap and then sends the bitmap to the display. So it's like a basic, you know, blitter and every 10 frames, I'm going to run the autofocus. So let's try this. Oh, I mean, even the file. Okay. So now it can go to the overhead. So you can kind of see how I'm like pulsing in and out a little bit. That's the autofocus mode that I'm trying to autofocus. And if I put, that's kind of dark here. Let me see if I can, you know, I can try to put some text in front of it and it will, it'll autofocus onto the text. The thing that's, you know, and this is like continuously autofocusing. And then you can actually hear it click sometimes too. So it does work. There's also a special capability. There's a special mode where you can draw like a square showing where the autofocus zone is because I think the different firmwares have different ways of like determining, like where, you know, where does it want to autofocus? Does it, does it want to autofocus in the center? Does it want to like do like a square like four signals? So there's like this one special capability where it kind of can like draw over the frame with the autofocus mode. So I might look at that next, but I just got this working. So that, that's good so far. And it means that I can start, you know, knowing that and knowing the pin out is, it means that I can take this design that I, oh, can you go to the computer? This design that was originally for the OV2640, which like doesn't have strobe and it doesn't have autofocus mode. And I'm going to redesign it for, you know, the 5640 as well. Like let's still work for the 2640, but what I'll do is I'll connect the two pins here, which are usually data zero and data one. I'm going to have it so you can connect those to the three volt and ground line. And that way, if you'd like to use it with autofocus mode, you can just like set a jumper. While I'm at it, I think I'm going to actually also put all these components on the back because I really think I need a lot more capacitors. Again, notice that the power supplies were like really like a little shaky because like there's actually quite a bit of power being used. In fact, one of the things I noticed is that if I ran the demo for like, you know, if I ran this like streaming image to TFT demo for a really long time, the camera actually like literally gets hot, which is surprising because it's only drawing like 150 milliamps, but it could be just like all that power is concentrated and it's not very well diffused. So the next thing I wanted to do is, in addition to this breakout, I wanted to make sure that this breakout could work with some sort of heat sink capability to add a passive heat sink, not a motorized heat sink or like a fan, but like a small passive heat sink that could maybe draw some of that heat off. You know, I never saw this with the 2640, but the 5640, you know, for whatever reason this camera like uses quite a bit more current. When I looked at the, yes, this is the pinout. So that's the autofocus. And I think this had the, the registry map and at the very bottom, I just missed it. AC characteristics, DC characteristics. So, input high, hold on. Yes, this is like the current draw. And, you know, it can get pretty high. It can get up to like 130 milliamps on the 1.5 volt DC power supply. So, you know, I definitely wanna have a heat sink for that. So I thought we could do that for the great search where I tried to find a little heat sink for my camera. All right, here we go. So just a heads up, we changed the great search music to be more retro-y, robotic sounding. One of our team members who is always doing our music, they just had a kid, so it'll be back soon. But that was courtesy of JP doing that roboticized version from the desk of Lady Aida to great search. I think it's a catchy tune because normally when you're trying to do electronics now, you're like, where in the world is that part I need? And then you think about the great search with DJ key. So that's where that song came from. And that's why we're doing it. And Lady Aida likes go to... A catchy tune you can hum while you're scaring for parts. So the part I'm looking for, just finished up Desk of Lady Aida where I talked about designing a camera breakout and the camera module I'm using draws enough current that it actually starts overheating and that the heat affects the visual quality.  And what I'll do is all the camera itself is glued onto the PCB. So maybe you can go to the overhead real fast and I can show. So you've got the camera breakout and then the camera, there's a little bit of a, there's a metal body and then there's this, I don't know if it's thermal but it's like this very thin tape. So you remove this and then I think this might be thermal. You remove this, place it in here and then this PCB is gonna extend a little bit farther but now this is stuck onto the back here and then over on the back of the PCB I'm gonna have a lot of vias through the ground plane and then have a little heat sink on the back. So the heat sink, it's gonna be, I think the largest it can be, it's gonna be basically between like eight millimeters and it looks like I can do like 10 millimeters. That's kind of, yeah, this is 10. So that'll cover it. I don't know if it makes sense to go much larger than 10. And I want something flat, rectangular with fins and I'll try a couple. There's the math behind it. You can calculate how much heat you're gonna disape but because it's going through a PCB with vias really I'm just gonna pick about a bunch of different heat sinks and try them all and just see which one works best. So let's go to the digit key and so it starts for heat sink. Take us to the heat sink category. So there's a lot of heat sinks. This category, it has 100,000 items. So there's a lot of different options. Let's start with just active and maybe normally stocking which is still 40,000 that are available now. The next thing is, there's all sorts of different types but looking, I basically want something like this, right? This is a 17 by 17 millimeter by nine millimeter and this is called a square with fins and then this is like a square with angle fins but I think I just want basically square finned. So looking at this option, I think, rectangular is also fine. I don't want to round this, I don't want round and then rectangular and square. Let's look at those. Okay, so that's like most of them to be honest. So yeah, so like lots of things. These are the clip on type which I don't want.  They're really cool but I can't use a clip on type. So I want maybe one that isn't a clip type but we can also do length and width instead. So remember I wanted something between like eight and 10 millimeters and then this is between eight and maybe I'll go up to 11-ish millimeters and that really cuts down the numbers. There's not that many small heat sinks. Like again, most heat sinks are for large chips but all these are really good. So like this heat sink, you can see it's, this is 10 millimeters I think. Sorry, this one is 10 by 10. This one is eight and a half by eight and a half. So I might try like one of these and one of these of course the larger the heat sink, the more heat you're gonna dissipate. There's also like these kind of the mega longs. This I don't think it's gonna work out. Of course it'll dissipate a ton of heat but people are just gonna knock this off of the back of the board. It has to be pretty compact so it doesn't like get in the way of things that are behind it. So I think what I'm gonna do, especially since this one, you know there's 50,000 in stock and they're like 55 cents a piece. Think this one is a good option. This is 10 by 10 millimeters, seven millimeters high, black anodized aluminum. It doesn't come with the thermal tape attached to it almost certainly so that's something that has to be done separately.  You definitely want to use a thermal tape and not just double sided tape because you want the adhesive to pass. You don't want to be an insulator, right? Because the one thing you don't want is it to insulate thermally. So this one is the one I want. This is the Asman WSW Components V2017B. We have a lot in stock. So that's kind of like a good sign because I could actually like ship this with the camera breakout board and not have to worry about it going out of stock anytime soon. And that's the very search? That's it. That's my heat sink. So we'll see everybody during the week Tuesday, J.P. Product Pick Wednesday. We have 3D Hangouts, Show and Tell, Ask an Engineer, Thursday J.P.'s Workshop and Friday Deep Dive. What's got in addition to Colin's labs that come out on Monday, Tuesday, Thursday and Friday. And- There's something every day. There's something every day. And then just today we posted up some of this camera stuff too on all the socials and more. So stay tuned for a big exciting week here on Moretronics. Channel Adafruit. Beep beep beep beep beep. Okay, bye everybody. Bye everybody.

Let's check that out right now. I'm gonna go into YouTube and we'll see what suggested videos are. Now, the biggest thing I hear from new YouTubers is that I don't have a lot of subscribers so I can't get any views. It's impossible for me to get views because I don't have any subscribers. This is videos that was suggested to me. And if you look through here, some of these are videos that I'm subscribed to, channels, that is, and others are not. Like, I do not subscribe to the Washington Post but for some reason, because of what I've watched online, they think that I should be watching that particular video. Now, here's the funny thing. If I were to click, let me scroll through here a little bit more, Invisible People, this one here got a million views, looks like it's homeless people. I do not subscribe to them. I do not subscribe to the Thrillist. I do subscribe to a couple of these others. So let me go ahead and click on this video here. And this looks like Santa Monica. Okay, now, when I clicked on this video, let me move this out of the way. When I clicked on this video, they gave me some up next or more suggested videos. It's funny because one of them is another mix of this particular video. Let's see what else we got in here, Invisible People. See what they did here. This particular one was by Invisible People and they said, well, gee, if he's gonna watch that, maybe he'll watch another one with Invisible People. So it's not like, and let me stop this, this is Invisible People here again. It's not like if you don't have a lot of subscribers, yours can't get suggested because that was suggested to me. I don't subscribe to it whatsoever. And now that I clicked on it, look at this. Invisible People, let's see if he gives me more here. Invisible People, Invisible People. Now it's saying, hey, he's interested in Invisible People. Look at all the videos it's suggesting to me now. It's amazing, guys. So this algorithm that YouTube has, you can get in the suggested area and it's possible to have 10 times as many views if you can get into that particular suggested area. Now, most YouTubers don't get this. They don't understand it. So it's gonna be easier for you to compete with it because you do get it now. You do understand it. No reason these suggested videos can't be you. Now, the way the algorithm works is that when you upload a video, it looks at the first date that you uploaded the video and then they look at how the viewers respond to your video and then they decide if they want to suggest it. So if you upload a video and some people like it and comment on it and they watch more on your channel, YouTube's gonna say, well, that's a good suggested video because we got good results. We got what we wanted. We got somebody to stay on our platform. And if you can get them to binge watch on your channel, that video's really gonna get suggested. Now, I'll tell you, this is so important. Once you've done your videos and you've got a few videos in there, you wanna go back and look at the analytics and see which videos are getting the most views because if all your videos on SEO are getting a lot of views, I would suggest you doing more videos on SEO and different versions of SEO or SEM because that's what your audience is asking for. And if you give them what they're asking for, your channel will grow. Additionally, you want to have your channel branded as you. Okay, let's check out my channel right here. This is my channel right here and I've got a scheduled live here, which is a really important thing to you guys, do some lives. And then I've got some of the most watched videos. This one here's got 56,000 views, 9,000 views. So I've also got it set up with my branding in here. It's a business type branding. I'll tell you, I wear T-shirts most days, but you gotta dress for the part, right? And it tells what I'm about. It says helping people start, run and grow online businesses. It's exactly what I'm about. It's got my website here and I say new videos every Monday, Wednesday and Friday. Now that's changed. I'm actually doing a Monday through Friday now, but they get that information there. They know what to expect. Online business training. This here goes to my website. This goes to a couple of my other web pages I have, okay? Free e-commerce course they can get right here. So there's a lot of stuff they can do and I've got this channel set up to where it's branded around me. Now the next thing you wanna do, and I see so many people missing this here, is once they've set up their channel and they got their videos and they're analyzing everything, they don't capitalize on the one big thing you can do and that is playlist. Every video on your channel needs to be in a playlist and the more playlist you have on your channel, the better off your SEO is gonna be. So if you've only got three playlists, I would suggest you adding some playlists, okay? And a video that you put in a playlist doesn't only have to be in that one playlist. It can be in multiple playlists. So if you've got a video and it's in e-commerce playlist, you could also put it under SEO if you talked about SEO in there. It could also be about credit card processing if you talked about credit card processing. So don't think in singular terms of I have a video, it's gonna be in this playlist. It can be in multiple playlists. If you do that, you're gonna have multiple URLs. URLs are what Google uses to find information on the internet. So if I do a video and I put it on my channel and I don't put it in a playlist, I have one URL. If I take that same video and I put it in four playlists, I'm gonna have the URL of that video and the other four URLs of those playlists. Now I've got five URLs for one video. This can drastically increase the chances of somebody seeing your videos. If you've been working on your channel and not getting results, come back to this video and watch it again. There's a lot of parts in here you may miss. If you miss those parts, that could cost you traffic, it could cost you money. So building a YouTube channel is not easy. I have so many people say, well, gee, I tried to do a YouTube channel, they don't work. It didn't work for you. And the reason it didn't work for you is because you did something wrong. No offense, no offense, you did something wrong because there's no way it can work for other people and it not work for you. The difference is they are doing something different. Maybe they uploaded more videos. Maybe they were more consistent. Building a YouTube channel is not what it used to be. It used to be you could come on here, do a few funny videos. You'd have thousands or millions of people subscribe to you. It's not like that anymore. Your competition is too stiff. That doesn't mean you can't do it. You just have to do all the things you need to do and be a little bit different, okay? Figure out your own way of doing things. And I'll tell you, the biggest part that people have fear about is getting started. They're like, geez, I don't even know what to start on. I don't know what to do. It doesn't matter how you start. What is important is that you do start because once you start, you're gonna start going in a particular direction and then you may change. You may go into another direction. But the point is if you keep doing it, you're gonna develop your own style. The truth is you'll never develop any style if you don't do it. If you do it, your own personality will eventually come out if you do it enough and if you do it over and over and over.  Trust me on this. Trust me on this. Put in the comments below.
