Large N expansion of the 2-matrix model, multicut case
arXiv:math-ph/0307052
Abstract
We present a method, based on loop equations, to compute recursively, all the terms in the large topological expansion of the free energy for the 2-hermitian matrix model, in the case where the support of the density of eigenvalues is not connected. We illustrate the method by computing the free energy of a statistical physics model on a discretized torus.
