通过(G′/G)方法得到了Sawada-Kotera方程及其推广方程的三种行波解.这些结果,有助于对非线性波在高维空间的动力学性质的了解.
In this paper,three types of traveling wave solutions of the Sawada-Kotera equation and it 's promotion equation are obtained by using-expansion method.These results help us to understand the nonlinear wave dynamics in high-dimensional space.
