Bo-Kui Chen, Yang Li, Han-Lin Chen, Bing-Hong Wang

摘要:

本文利用指数函数法,借助于符号计算系统,求出了变系数Burgers-Fisher方程的广义行波解。结果表明,指数函数法在符号计算的帮助下,为求解数学物理中的变系数非线性发展方程提供了一种直观而有力的数学工具.

英文摘要:

In this paper, the exp-function method with the aid of symbolic computational system is used to obtain generalized travelling wave solutions of a Burgers-Fisher equation with variable coefficients. It is shown that the exp-function method, with the help of symbolic computation, provides a straightforward and powerful mathematical tool to solve the nonlinear evolution equation with variable coefficients in mathematical physics.
