摘要
基于微分特征列法和微分带余除法,给出了利用拟微分算子构造非线性发展方程1+1维和2+1维Lax表示的新算法.新算法减少了运算步骤,简化了计算过程,是微分特征列法在可积系统领域一个新的应用.
Based on differential characteristic chain method and differential division with remainder,a new algorithm for constructing 1+1-dim and 2+1-dim Lax representations of nonlinear evolution equations with pseudodifferential operators is presented.In new algorithm,the calculation steps are decreased,and the process is simplified.It is a new application of differential characteristic set method in integrable systems.
