摘要
从一个Hirota双线性方程出发,利用变换u=2(lnf)x,得到一个变系数的广义(3+1)维Kadomtsev-Petviashvili(GKP)方程,并借助 Maple软件,得到了该(3+1)维 GKP方程的 Lump 解,同时绘制了解的立体图和等高线图.
Abstract
Starting from a Hirota bilinear equation and using a transformation u=2(lnf)x we derive a new generalized(3+1)dimensional Kadomtsev-Petviashvili(GKP)equation with variable coefficients.By using Maple software,we obtain the Lump solutions of the(3+1)dimensional GKP equation.At the same time,we depict both the three-dimensional image and contour images of the obtained solutions.
