Description
In the limit of infinite numbers of coulours in Yang-Mills theory, the interplay between volume and group degrees of freedom has led to the concept of volume independence through Eguchi-Kawai reduction. We will discuss an attempt to extend this idea beyond the large N limit. A few non-perturbative examples will be presented, including the running of the SU(N) ’t Hooft coupling and the 2+1 dimensional glueball spectrum.
