用(1/G)-展开法求修正Kawahara方程的孤立波解

Solitary Wave Solutions for Modified Kawahara Equation by(1/G)-expansion Method

利用(1/G)-展开法,借助于计算机代数系统M athem atica,获得了修正Kawahara方程的孤立波解,这里的G=G(ξ)是一阶线性常微分方程的解,(1/G)-展开法可看作是(G′/G)-展开法的一种特殊情形。

By using the(1/G)-expansion method and with the aid of computer algebra system Mathematica,the solitary wave solutions of the modified Kawahara equation are successfully obtained,where G=G(ξ) satisfies a linear first order ordinary differential equation.The(1/G)-expansion method can be thought of as a special case of the(G′/G)-expansion method proposed recently.
