摘要
利用达布变换方法,推导出逆时空非局域Fokas-Lenells方程周期背景上的复合波解。首先,利用Kaup-Newell Lax对,给出一重达布变换和N重达布变换的行列式表示。选取平面波解,得到kink型周期波、呼吸子、亮暗孤子及其复合波解。另外,构造了半退化达布变换,获得怪波、呼吸子及其复合波解。
The hybrid wave solutions on the periodic background for the nonlocal reverse space-time Fokas-Lenells equation are derived by using Darboux transformation method in the paper.Firstly,the determinant representations of one-fold Darboux transformation and N-fold Darboux transformation are expressed by using the Kaup-Newell spectrum problem.And then,the kink-type periodic wave,the breather solutions,the light and dark soliton solutions,and hybrid wave solutions are obtained by selecting the plane wave solution.Furthermore,the solution of the rouge waves,the breathers and hybrid waves are obtained by constructing the semi-degenerate Darboux transformation.
