Large N expansion of the 2-matrix model, multicut case.

Bertrand Eynard

Résumé

We present a method, based on loop equations, to computerecursively, all the terms in the large $N$ topologicalexpansion of the free energy for the 2-hermitian matrixmodel, in the case where the support of the density ofeigenvalues is not connected.We illustrate the method by computing the free energy of astatistical physics model on a discretized torus.
