摘要:

为了构造(2+1)维一般Calogero-Bogoyavlenskii-Schiff系统的无穷序列类孤子新解,首先引入了可转化为Riccati方程的新的辅助方程及其新解,其次给出了Riccati方程的新解、Bäcklund变换和解的非线性叠加公式。在此基础上,借助符号计算系统Mathematica, 构造了(2+1)维一般Calogero-Bogoyavlenskii-Schiff系统的无穷序列类孤子新解。这些解由指数函数,三角函数和有理函数复合组成。

Abstract:

To construct the new infinite sequence soliton-like solutions of the (2+1)-dimension general Calogero-Bogoyavlenskii-Schiff system, first, the new auxiliary equation that can be changed to the Riccati equation and its new solutions are presented, then the new solutions, B?cklund transformation and the nonlinear superposition formula of solutions of the Riccati equation are presented. Depending on these and with the help of Mathematica, the new infinite sequence soliton-like solutions of the (2+1)-dimension general Calogero-Bogoyavlenskii-Schiff system are constructed. The solutions are consisting of exponential function, trigonometric function and rational function.

Key words: nonlinear equation, auxiliary equation, (2+1)-dimension general Calogero-Bogoyavlenskii-Schiff system, new infinite sequence soliton-like solutions
