[APDE Unit Seminar] Optimal Regularity for the 2D Euler Equations in the Yudovich Class

Title: Optimal Regularity for the 2D Euler Equations in the Yudovich Class

 

Abstract: We analyze the optimal regularity that is exactly propagated by a transport equation driven by a velocity field with BMO gradient. As an application, we study the 2D Euler equations in cases where the initial vorticity is bounded. This talk is based on joint work with David Meyer and Christian Seis.
