With a projective equation and a linear variable separation method, this paper derives new families of variable separation solutions (including solitory wave solutions, periodic wave solutions, and rational function solutions) with arbitrary functions for (2+1)-dimensional generalized Breor-Kaup (GBK) system. Based on the derived solitary wave excitation, it obtains fusion and fission solitons. 相似文献

In the paper, the variable separation approach, homoclinic test technique and bilinear method are successfully extended to a （1 ＋1）-dimensional Caudry-Dodd-Gibbon-Sawada-Kortera （CDGSK） system, respectively. Based on the derived exact solutions, some significant types of localized excitations such as standing waves, periodic waves, solitary waves are simultaneously derived from the （1＋1）-dimensional Caudry-Dodd-Gibbon-Sawada-Kortera system by entrancing appropriate parameters. 相似文献
