Abstract

We study the large N saddle points of weakly coupled N = 4 super Yang- Mills theory on S1 × S3 that are described by a commuting matrix model for the seven scalar fields {A0,ΦJ}. We show that at temperatures below the Hagedorn/‘deconfinement’ transition the joint eigenvalue distribution is S1 × S5....
