Analysis Seminar
Two dimensional gravity water waves at low regularity: global solutions.
Mihaela Ifrim, University of Wisconsin–Madison
1:00 PM - 2:00 PM
Zoom ID 783 353 8838
This talk is about the second installment of a series of papers concerned with low regularity solutions for the water wave equations in two space dimensions. Our focus here is on global solutions for small and localized data. Such solutions have been proved to exist earlier in much higher regularity. The goal of this talk is to explain how these results were improved, specifically show global well-posedness under minimal regularity and decay assumptions for the initial data. One key ingredient here is represented by the balanced cubic estimates. Another is the nonlinear vector field Sobolev inequalities, an idea first introduced by Ifrim and Tataru in the context of the Benjamin-Ono equations. This is joint work with Albert Ai and Daniel Tataru.
