Integrable lattice equations with vertex and bond variables

Exactly Solvable and Integrable Systems 2015-05-28 v3 Dynamical Systems

Abstract

We present integrable lattice equations on a two dimensional square lattice with coupled vertex and bond variables. In some of the models the vertex dynamics is independent of the evolution of the bond variables, and one can write the equations as non-autonomous "Yang-Baxter maps". We also present a model in which the vertex and bond variables are fully coupled. Integrability is tested with algebraic entropy as well as multidimensional consistency
