備注： Abstract: In this talk, we will introduce peakon and cuspon equations and present a basic approach how to get peakon and cuspon solutions. Those equations include the well-known Camassa-Holm (CH), the Degasperis-Procesi (DP), and other new peakon equations. Interesting thing is that an integrable equation may have no classical smooth solitons.
In the talk, I will illustrate this feature through two new integrable equations that I found recently. Later, I take the CH case as a typical example to show how we obtain the peaked solitons and parametric solutions on symplectic submanifold.
