Abstract:Based on the Hirota bilinear form of the generalized (3+1) dimensional variable-coefficient B-type Kadomtsev-Petviashvili equation,~the lump and lump-type solutions are generated through symbolic computation, whose analyticity can be easily achieved by taking special choices of the involved parameters.~The property of solutions are investigated and exhibited vividly by three dimensional plots and contour plots.

构造(3+1)维变系数的gBKP方程的两类有理函数解
摘要:本文研究了流体力学领域中的扩展的(3+1)维变系数的非线性BKP方程。应用Bell多项式理论,将方程转化为双线性形式的方程。再借助符号计算工具,得到方程的两类新型有理函数解并通过绘制3维立体图形及等值线图的方式分析解的相关性质。
