CMI Workshop: Solvability and Spectral Instability
September 18-21, 2007
The workshop is in the honor of the 50th anniversary of Hans Lewy's famous paper ("An example of a smooth linear partial differential equation without solution", Ann. of Math. (2) 66 (1957), 155-158) which gave the first example of a PDE that was not solvable.
The workshop will be held at the Clay Mathematics Institute Headquarters in Cambridge, Massachusetts..
