变系数(2+1)维Broer-Kaup方程新的类孤子解

New soliton-like solutions to (2+1)-dimensional Broer-Kaup equation with variable coefficient

通过对求解非线性偏微分方程推广的tanh函数法的进一步改进,获得了变系数(2+1)维Broer Kaup方程许多新的类孤子解.

With the aid of further improving some procedures of the tanh-function generalized by solving nonlinear partial equations, we obtain many new soliton-like solutions to the (2+1)-dimesional Broer-Kaup equation with variable coefficient.
