摘要
主要研究构造非线性演化方程的Backlund变换的新途径.首先从一个连续的谱问题出发,借助于Lax对的非线性化方法,推导出连续的非线性演化方程,然后应用谱问题的相容性,构造了两个非线性微分差分方程,这两个方程恰好是一个连续的非线性演化方程的Backlund变换.
In this paper, we mainly construct two Backlund transformations of the nonlinear evolution equation. Through nonlinearization technique,we get continuous nonlinear evolution equation from the continuous eigenvalue problem,and then we have constructed two differential difference equations with the help of the compatibility, these equations can be as Backlund transformations of the nonlinear evolution equation.
