介绍,给出了(2+1)维类浅水波方程的有理解,最后比较了有理解的图像并进行了分析。

2 (2+1)维类浅水波方程及其广义双线性形式

4 总结

通过广义双线性方法讨论了(2+1)维类浅水波方程,并利用多项式函数求解(2+1)维类浅水波方程,从而获得了九类不同的有理解。研究过程中用到的基本理论是广义双线性算子[18]。

研究过程中对有理解图像进行简单的分析之后发现(6)式的有理解,相对于坐标轴具有良好的对称性。这些有理解中有的是怪波解,怪波解在气象学、海洋学等领域具有重要的物理意义。因此,有理解是存在讨论和研究价值的。可设想文中提出的此类有理解概括了类浅水波方程的所有有理解。

在研究过程中,通过同样的方法还得到了(3+1)维类浅水波方程的有理解,但(3+1)维方程的有理解与文中得到的(2+1)维方程的有理解是类似的,所以在此文中暂不讨论(3+1)维类浅水波方程。此外,文中对有理解的求解的过程对讨论类浅水波方波的Wronskian行列式解[19]Pfaffian解是非常有意义的。最重要的是,通过本文的研究可以向大家证明高阶微分方程的有理解是非常有研究价值的。
