Fornberg-Whitham方程的一类有界行波解

A type of bounded traveling wave solutions for the Fornberg-Whitham equation

Jiangbo Zhou, Lixin Tian

摘要:

本文利用分支方法,成功地发现了Fornberg-Whitham方程存在一类行波解,称为类扭结波解和反类扭结波解。它们定义在某些半最终有界区域上,具有扭结波和反扭结波的性质。得到了它们的隐式表达式。对于具体数据,给出了隐函数的图形,并进行了数值模拟。结果表明,我们的理论分析与数值模拟一致。

英文摘要:

In this paper, by using bifurcation method, we successfully find the Fornberg-Whitham equation has a type of traveling wave solutions called kink-like wave solutions and antikinklike wave solutions. They are defined on some semifinal bounded domains and possess properties of kink waves and anti-kink waves. Their implicit expressions are obtained. For some concrete data, the graphs of the implicit functions are displayed, and the numerical simulation is made. The results show that our theoretical analysis agrees with the numerical simulation.
