(2+1)维Broer-Kaup-Kupershmidt系统的孤子解及孤子间的相互作用

Soliton Solutions and the Interaction between Solitons for the(2+1)-Dimensional Broer-Kaup-Kupershmidt System

利用Riccati方程投射法和变量分离法,得到(2+1)维Broer-Kaup-Kupershmidt(BKK)系统的精确解。根据得到的孤波解,构造出该系统新颖的局域结构,研究了孤子间的相互作用。

By the Riccati equation mapping method and a variable separation method,a series of exact solutions of the(2+1)-dimensional Broer-Kaup-Kupershmidt system(BKK)is derived.Based on the derived solitary wave solution,we obtain some novel localized structures and study the interaction between solitons of the system.
