题目: Stability of peakons of the shallow water modeling with cubic nonlinearity


摘要:

In this talk, I will start by demonstrating the underlying complexity of the physical system,  and then I will discuss  possible simplifications in the "shallow water" regime along with the relevant physical phenomena. In particular, I will derive some simplified nonlocal shallow-water models with cubic nonlinearity, such as integrable Novikov and Modified Camassa-Holm-type equations. It is shown these approximating model equations possess a single peaked soliton and multi-peakon solutions. Finally I will prove the single peaked soliton is orbitally stable in the energy space.
