Abstract:
In this talk, we will talk about the long time behavior of the two dimensional water waves. In the first part we discuss the long time existence of water waves with concentrated vorticity. We show that the water waves with small initial slope and velocity, coupled with a pair of counter-rotating point vortices which travels downward, remains small and smooth for a long time. In the second part we discuss the NLS approximation of the water waves. In particular, I will discuss the rigorous justification of the Peregrine soliton and the nonlinear instability of the Stokes waves.
