报告摘要:

In this talk, we focuse on dark solitons and periodic solitary wave solutions for Kundu-Eckaus equations without and with a strong generic delay, respectively. First, in terms of the dynamic system arguments, new dark solitons and periodic solitary wave solutions for the Kundu-Eckaus equation without delay are obtained by integrating along different orbits. Then, the limits and modulation stability of the solutions of the Kundu-Eckaus equation are investigated. Finally, the existence of two dark solitons and two periodic solitary wave solutions for Kundu-Eckhaus equations with a strong generic delays is proven via geometric singular perturbation theory.
