Abstract

We solve the loop equations of the hermitian 2-matrix model to all orders in the topological 1/N21/N^2 expansion, i.e. we obtain all non-mixed correlation functions, in terms of residues on an algebraic curve. We give two representations of those residues as Feynman-like graphs, one of them involving only cubic vertices.
