题目：Superregular breathers and general rogue waves in the scalar and vector nonlinear Schrödinger equations

     摘要：In this talk, general higher-order freak wave solutions of the scalar and coupled nonlocal nonlinear Schrodinger equations can be calculated theoretically via a Darboux transformation and a separation of variable technique. This family of solutions are given in separation of variables form. Moreover, in order to understand these obtained solutions better, the main characteristics of these obtained freak wave solutions are discussed clearly and conveniently. They show that the dynamics of these solutions exhibits rich patterns, most of which have no counterparts in the corresponding local equation. Finally, with the dressing method and an orthogonal transformation, we generate the multibreather solutions to the Manakov model.
