In number theory, one form of this quantity is sensitive to the first terms of a sequence, being zero ifone is not in the set and less than one-half if two is not in the set.

In number theory, one form of this quantity is sensitive to the first terms of a sequence, being zero ifone is not in the set and less than one-half if two is not in the set. That form of this quantity is contrastedwith another form equal to the limit as n goes to infinity of the number of integers less than n in a set, overn; that form is zero for a finite sequence. Those two forms are the Schnirelmann and asymptotic types.According to the Baire category theorem, the intersection of countably many open sets with this property isnonempty, and a complete metric space is not the union of countably many closed sets that nowhere havethis property. A subset S of a metric space X has this property if and only if there is some point of S in eachnonempty open set of X. The Cantor set is an example of a closed set that lacks this property everywhere.For 10 points, identify this term that names a function in probability that is the derivative of the cumulativedistribution function.
