DESCRIPTION:Spectral Geometry Seminar\n\nTitle: Schrödinger operators with 
 complex potentials: Beyond the Laptev-Safronov conjecture.\n\nAbstract: I 
 will report on recent progress concerning eigenvalues of Schr¨odinger oper
 ators with complex potentials. This talk can be seen as a continuation of 
 the recent talk by Sabine B¨ogli (Durham) in the same seminar series\, whe
 re a counterexample to the Laptev-Safronov conjecture was presented. I wil
 l explain how techniques from harmonic analysis\, particularly those relat
 ed to Fourier restriction theory\, can be used to prove upper and lower bo
 unds. Then I will present new results that show that in some cases one can
  go beyond the threshold of the counterexample.\n\n \n\nVisit the Web site
