几种浅水波非线性偏微分方程的孤波解

Solitary wave solutions of several nonlinear PDEs modeling shallow water waves

Nikolay K. Vitanov, Tsvetelina I. Ivanova

摘要:

本文应用最简方程法的一种形式,即修正的最简方程法,求解一类方程的精确行波解,其中一类方程是粘性流体中浅水波的非线性偏微分方程(Topper-Kawahara方程)。作为最简单的方程,我们使用Riccati方程的一个版本。我们从所研究的一类方程中得到了两个精确的行波解,并讨论了对其中一个解施加边界条件的问题。

英文摘要:

We apply the version of the method of simplest equation called modified method of simplest equation for obtaining exact traveling wave solutions of a class of equations that contain as particular case a nonlinear PDE that models shallow water waves in viscous fluid (Topper-Kawahara equation). As simplest equation we use a version of the Riccati equation. We obtain two exact traveling wave solutions of equations from the studied class of equations and discuss the question of imposing boundary conditions on one of these solutions.
