报告摘要：In my talk, I will introduce integrable peakon and cuspon models developed in recent years and present a basic approach 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 the b-family quadratic and cubic peakon models with peakon and weak-kink solutions. In the end of my talk, some open problems associated with eigenvalue problems are also addressed for discussion.
