DESCRIPTION:Title: <a href="https://researchseminars.org/talk/anpdews/30/"
 >Unique continuation properties for nonlocal operators</a>\nby María Áng
 eles García-Ferrero (University of Heidelberg) as part of HA-GMT-PDE Semi
 nar\n\n\nAbstract\nRoughly speaking\, a unique continuation property state
 s that a solution of certain partial differential equation is determined b
 y its behaviour in a subset. In this talk we will see this kind of propert
 ies\, including their strong and quantitative versions\, for some classes 
 of nonlocal operators like the Hilbert transform\, which arise in medical 
 imaging\, or the (higher order) fractional Laplacian. The results I will p
 resent rely on commonly used tools as Carleman estimates and the Caffareli
 -Silvestre extension\, but also on two alternative mechanisms. As an appli
 cation we will see Runge approximation results.\n\nThis is joint work with
  Angkana Rüland.\n
