Completely Xsymmetric Smatrices corresponding to theta functions and models of statistical mechanics
Abstract
We consider general expressions of factorized Smatrices with Abelian symmetry expressed in terms of θfunctions. These expressions arise from representations of the Heisenberg group. New examples of factorized Smatrices lead to a large class of completely integrable models of statistical mechanics which generalize the XYZmodel of the eightvertex model.
