摘要

寻求高维非线性偏微分方程的精确解近年来在数学和物理领域受到了极大的关注。本文研究了描述不可压缩流体中非线性波传播的(3+1)维Boiti-Leon-Manna-Pempinelli方程的精确解。首先，利用扩展同斜检验方法，得到了(3+1)维boti - leon - manna - pempinelli方程的8种非行波解。然后，结合改进的tanh函数方法和新的ansatz解，得到了(3+1)维boit - leon - manna - pempinelli方程的大量新的精确非行波解。这些结果不仅包括许多其他文献的结果，而且还包括一些新的精确非行波解。并将这些解中包含的任意函数作为特殊函数，给出了它们的精确扭结波解、周期孤立波解和奇异孤立波解。

ABUNDANT NEW NON-TRAVELING WAVE SOLUTIONS FOR THE (3+1)-DIMENSIONAL BOITI-LEON-MANNA-PEMPINELLI EQUATION

Seeking exact solutions of higher-dimensional nonlinear partial differential equations has recently received tremendous attention in mathematics and physics. In this paper, we investigate exact solutions of (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation which describes nonlinear wave propagation in incompressible fluid. Firstly, by means of extended homoclinic test approach, we get eight kinds of non-traveling wave solutions of (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation. Then, combining the improved tanh function method and new ansatz solutions, we obtain abundant new exact non-traveling wave solutions of (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation. These results include not only many results obtained in other literatures, but also some new exact non-traveling wave solutions. Moreover, the exact kink wave solutions, periodic solitary wave solutions and singular solitary wave solutions are given when arbitrary functions contained in these solutions are taken as some special functions.
