DESCRIPTION:Speaker: Angkana Rüland\nhosted by Jan Maas\nAbstract: In this
  talk I discuss a nonlocal inverse problem\, the fractional Calderón prob
 lem. This is an inverse problem for a fractional Schrdinger equation in wh
 ich one seeks to recover information on an unknown potential by exterior m
 easurements. In the talk\, I prove uniqueness and stability of the "infini
 te data problem"and then address the recovery question. This also yields (
 at firstsight) surprising insights on the uniqueness properties of the inv
 erse problem in that it turns out that a single measurement suffices to un
 iquely recover the potential.These properties are based on the very strong
  unique continuation and approximation properties of fractional Schrdinger
  operators\, which are of independent interest and which I also discuss in
  the talk.This is based on joint work with T. Ghosh\, M. Salo and G. Uhlma
 nn.
