A Simple Fast Method in Finding Particular Solutions of Some Nonlinear PDE
-
摘要: 简单介绍了应用一个简洁的“试探函数法”求解非线性偏微分方程的基本步骤,主要研究了两大类方程,一类是Burgers方程或KdV方程的推广,另一类是具有特殊非线性反应率的Fisher方程.不难看出,这个方法是简洁的,并且可望进一步扩展.Abstract: The "trial function method"(TFM for short) and a routine way in finding traveling wave solutions to some nonlinear partial differential equations(PDE for short) wer explained.Two types of evolution equations are studied,one is a generalized Burgers or KdV equation,the other is the Fisher equation with special nonlinear forms of its reaction rate term.One can see that this method is simple,fast and allowing further extension.
