DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Inverse/20/"
 >The fixed angle scattering problem</a>\nby Rakesh (University of Delaware
 ) as part of International Zoom Inverse Problems Seminar\, UC Irvine\n\n\n
 Abstract\nWe first discuss our (with Mikko Salo) uniqueness result for the
  fixed angle scattering problem that the acoustic property (zeroth order c
 oefficient) of a medium is uniquely determined by the far-field data\, mea
 sured in all directions for all frequencies\, associated with two incoming
  plane waves from opposite directions. Next we discuss our (with Venky Kri
 shnan and Soumen Senapati) uniqueness result for a similar problem where t
 he coefficient depends on space and time variables. \n\nBoth problems are 
 formally determined and the results are proved by showing Lipschitz stabil
 ity for two inverse problems for hyperbolic PDEs with boundary data\, usin
 g a variation of the Bukhgeim-Klibanov method.\n
