arXiv:hep-th/0504116 · doi:10.1088/1126-6708/2006/03/014

Abstract

We present a diagrammatic technique for calculating the free energy of the Hermitian one-matrix model to all orders of 1/N expansion in the case where the limiting eigenvalue distribution spans arbitrary (but fixed) number of disjoint intervals (curves).
