摘要
研究精确求解某些非线性演化偏微分方程的4种φ(ξ)展式法。用这些方法分别获得了七阶SK-Ito方程、五阶KdV方程、三阶KdV方程、三阶Joseph-Egri方程的许多类型的新行波解。这些方法还可用于求解其它一些非线性演化偏微分方程。
Four types φ(ξ) expansion methods for accurately solving nonlinear evolution partial differential equations were investigated in this paper. Many types of new travelling wave solutions to the seventh order SK-Ito equation, the fifth order KdV equation, the third order KdV equation, and the third order Joseph-Egri equation were found by using these φ(ξ) expansion methods.These methods can also be used to solve some other nonlinear evolution partial differential equations.
