本文利用平衡点的平移和拓展的三波测试方法,着重讨论了(2W1)维Kadomtsev-Petviashvili方程所描述的动力系统的时空分岔问题,得到了一些新的、重要的结果.
In this work, by using translation of equilibrium and extend three-wave type of ans~tz approach, we discuss the spatiotemporal bifurcation of soliton for the (2+1)- dimensional Kadomtsev-Petviashvili equation and obtain some new conclusions.
