SUMMARY:Plenary Lecture 13: Shock Reflection\, von Neumann conjectures\, a
 nd free boundary problems - Feldman\, M (University of Wisconsin-Madison)
DTSTART:20140627T123000Z

CONTACT:Mustapha Amrani
DESCRIPTION:Co-author: Gui-Qiang Chen (Oxford) \n\nWe discuss shock reflec
 tion problem for compressible gas dynamics\, and von Neumann conjectures o
 n transition between regular and Mach reflections. Then we will talk about
  recent results on existence of regular reflection solutions for potential
  flow equation up to the detachment angle\, and discuss some techniques. T
 he approach is to reduce the shock reflection problem to a free boundary p
 roblem for a nonlinear equation of mixed elliptic-hyperbolic type. Open pr
 oblems will also be discussed.\n
