变换有理函数法与3+1维Jimbo-Miwa方程的精确解

A transformed rational function method and exact solutions to the 3+1 dimensional Jimbo-Miwa equation

Wen-Xiu Ma, Jyh-Hao Lee

摘要:

提出了一种利用有理函数变换直接求非线性偏微分方程精确解的方法。新方法统一了双曲正切函数型方法、齐次平衡法、指数函数法、映射法和F-展开型方法,使非线性方程组的求解过程更加系统和方便。其核心是寻找由给定的偏微分方程转化为变系数常微分方程的有理解。作为应用,利用贝克隆变换讨论了3+1维Jimbo-Miwa方程的精确解的构造问题.

英文摘要:

A direct approach to exact solutions of nonlinear partial differential equations is proposed, by using rational function transformations. The new method provides a more systematical and convenient handling of the solution process of nonlinear equations, unifying the tanh-function type methods, the homogeneous balance method, the exp-function method, the mapping method, and the F-expansion type methods. Its key point is to search for rational solutions to variable-coefficient ordinary differential equations transformed from given partial differential equations. As an application, the construction problem of exact solutions to the 3+1 dimensional Jimbo-Miwa equation is treated, together with a Bäcklund transformation.
