Four-Component Liouville Integrable Models and Their Bi-Hamiltonian Formulations
JIN-YUN YANG, Wen‐Xiu Ma
Abstract
We aim at presenting Liouville integrable Hamiltonian models with four dependent variables from a specific matrix eigenvalue problem. The Liouville integrability of the resulting models is exhibited through formulating their bi-Hamiltonian formulations. The basic tools are the Lax pair approach and the trace identity. Two illustrative examples consist of novel four-component coupled integrable models of second-order and third-order
