High Energy Physics - Theory 2007-05-23 v1

Abstract

We derive a set of bilinear functional equations of Hirota type for the partition functions of the sl(2)sl(2) related integrable statistical models defined on a random lattice. These equations are obtained as deformations of the Hirota equations for the KP integrable hierarchy, which are satisfied by the partition function of the ensemble of planar graphs.
