考虑一类包含相对论Toda链的离散微分方程,其特征为一个六变量的任意函数。在这门课中,我们导出了三个条件,可以用来检验任意给定方程的可积性。在推导这些条件时,我们使用更高的对称性来区分通过逆散射方法可积的方程。
We consider a class of discrete-differential equations that contains the relativistic Toda chain and is characterized by one arbitrary function of six variables. We derive three conditions that allow testing the integrability of any given equation in this class. In deriving these conditions, we use higher symmetries distinguishing the equations that are integrable via the inverse scattering method.
