One method of calculations in this theory involves discretizing space and time taking the spacing of points to zero.
Objects that this theory considers composite are taken to be topological solitons of a non-linear sigma model, according to the Skyrme model. t' Hooft came up with a way to do perturbation theory in this theory by using a certain number as a coupling constant, and working in the limit where that number goes to infinity. One method of calculations in this theory involves discretizing space and time taking the spacing of points to zero. That method is possible because the couplings in this theory go to zero as distance goes to zero. The fundamental degrees of freedom in this theory are never observed alone due to another major property of this theory: they are always in groups that are color neutral. Those two properties are confinement and asymptotic freedom. For 10 points, name this theory of the strong force.
