DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/83/">Th
 e regularity of the boundary of a vortex patch and commutators of singular
  integrals</a>\nby Joan Verdera (Universitat Autònoma de Barcelona) as pa
 rt of Online Seminar "Geometric Analysis"\n\n\nAbstract\nI will introduce 
 briefly the vorticity form of the Euler equation in the plane and show how
  singular integrals appear immediately. Then I will introduce vortex patch
 es and the problem of regularity of the boundary. I will describe some ele
 ments of a short proof I have found recently\, which also solves the regul
 arity problem for other transport equations. Commutators of singular integ
 rals play a key role\, as it is well-known.\n
