DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IMS/76/">Loc
 al smoothing for the wave equation in 2+1 dimensions</a>\nby Ruixiang Zhan
 g (IAS\, Princeton) as part of PDE seminar via Zoom\n\n\nAbstract\nSogge's
  local smoothing conjecture for the wave equation predicts that the local 
 L^p space-time estimate gains a fractional derivative of order almost 1/p 
 compared to the fixed time L^p estimates\, when p>2n/(n-1). Jointly with L
 arry Guth and Hong Wang\, we recently proved the conjecture in R^{2+1}. I 
 will talk about our proof and explain several important ingredients such a
 s induction on scales and an incidence type theorem.\n
