Global regularity for 2D gravity water waves with two retreating point vortices
Lei Su, Qingtang Su, Siwei Wang
We prove global well-posedness for the two-dimensional infinite-depth gravity water wave system coupled to a pair of point vortices of opposite strengths. The vortex dipole is init…

A New Structure for the 2D water wave equation: Energy stability and Global well-posedness
Qingtang Su, Siwei Wang
We study the two-dimensional gravity water waves with a one-dimensional interface with small initial data. Our main contributions include the development of two novel localization…
