摘要:

该文利用Hirota双线性形式和广义三波测试法构建了(3+1)维Potential-Yu-Toda-Sasa-Fukuyama方程新的多周期孤子解.其中有一些完全新的周期孤子解,包括周期性交叉扭结波解、周期性双孤立波解和呼吸型双孤立波解.借助于符号计算,呼吸子和孤子的相互作用及传播特点被一些图形展示出来.

关键词: Hirota双线性形式, 多孤子解, 符号计算

Abstract:

By using the Hirota's bilinear form and generalized three-wave approach, we construct multiple periodic-soliton solutions of (3+1)-dimensional potential-YTSF equation. Some entirely new periodic-soliton solutions are presented including periodic cross-kink wave, periodic two-solitary wave and breather type of two-solitary wave solutions. With the aid of symbolic computation, propagation characteristics and interactions of breathers and solitons are shown with some figures.

Key words: Hirota's bilinear form, Multiple soliton solutions, Symbolic computation
