Rigidity and flexibility of stationary solutions of the Euler equations
Javier Gomez-Serrano - Brown University and Universitat de Barcelona
Date & time: Wednesday, 02 February 2022 at 9:30AM - 10:30AM
Abstract: In this talk, I will discuss characterizations of stationary solutions of the 2D Euler equations in two different directions under different assumptions: rigidity (is every stationary solution radial?) and flexibility (do there exist non-radial stationary solutions?). The proofs will have a calculus of variations' flavor, a new observation that finite energy, stationary solutions with simply-connected vorticity have compactly supported velocity, and an application of the Nash-Moser iteration procedure. Based on joint work with Jaemin Park, Jia Shi and Yao Yao.
