 >Uniqueness for the fractional Calderon problem with quasilocal perturbati
 ons</a>\nby Giovanni Covi (Heidelberg University) as part of International
  Zoom Inverse Problems Seminar\, UC Irvine\n\n\nAbstract\nWe will be talki
 ng about the fractional Schrodinger equation with quasilocal perturbations
 . Quasilocal operators are a special kind of nonlocal operators transformi
 ng compactly supported functions into functions of unbounded support with 
 a decay estimate at infinity. These include\, among the others\, convoluti
 ons operators against Schwartz functions. We will show that both qualitati
 ve and quantitative unique continuation and Runge approximation properties
  hold in the assumption of sufficient decay. The results are then used to 
 show uniqueness in the inverse problem of retrieving a quasilocal perturba
 tion from DN data under suitable geometric assumptions. This work generali
 zes recent results regarding the locally perturbed fractional Calderon pro
 blem\, and is based on the following paper: https://arxiv.org/abs/2110.110
