一族非线性微分-差分方程的可积耦合系统
An Integrable Coupling for a Nonlinear Differential-difference Problem
【摘要】 基于一个离散等谱问题,构建了一族离散可积耦合,利用离散零曲率方程,导出了相应离散的非线性微分-差分方程,进而确定了其相应的Lax可积的离散非线性系统.
【Abstract】 Based on a new discrete iso-spectral problem,a hierarchy of integrable nonlinear discrete coupling system is devised.Using the discrete zero curvature equations,the discrete differential-difference equation is deduced,and corresponding nonlinear system of discrete and integrable is validated.
