报告题目：Integrable Models with Peakon Solutions of Non-traveling Wave Type

报告人：乔志军 教授

报告摘要：In my talk, I willintroduce integrablepeakon andcuspon modelsdevelopedin recentyears and present a basicapproach how to get the peakon models.We will see that the well-known CH equation is included in the negative order CH hierarchy while the Dym type equation is included in the positive order CH hierarchy. In particular, the CH peakon equation is extended to theb-family quadraticand cubic peakon models with peakon and weak-kink solutions.We will also presentnew type of peakon solutions of partial differential equations, called rogue peaked solitons provided with an non-traveling wave. Some linear and nonlinearmodels are takento illustrate therogue peakon solutions. In the end of my talk, some open problems arealso addressed for discussion. Some of this work is the joint with my student Zhenteng Zeng.
