報告摘要: In this talk, we will introduce integrable peakon models developed in recent years and present a basic approach how to get the peakon solutions of integrable equations. In particular, the CH peakon equation is extended to the b-family quadratic and cubic peakon models (FORQ, MOCH, Novikov Equations etc) with peakon and weak-kink solutions. We will also talk about a new CH-type equation – fifth-order CH equation and present new type solutions – pseudo-peakon solutions and their interactions. Some work in the talk is joint with Dr. BQ Xia and Dr. E Reyes. Open problems are proposed in the end for discussion.
