In this paper we explain how space-time localized waves can be generated by introducing nonisospectral effects which are......

本文综述了不变几何曲线流和可积系统关系的相关研究.证明了包括KdV方程、修正KdV方程、非线性可积薛定谔方程和Burgers方程在内的......

In this paper we consider a class of polynomial planar system with two small parameters,ε and λ,satisfying 0 ＜ ε ＜＜ λ ＜＜ ......

In this paper, the symmetries of the Burger and Calogero equation are found. These symmetries form the same Lie algebra.......
