Aleksey Kostenko: On the absolutely continuous spectrum of Schrödinger operators and strings.

Abstract: The study of spectral types of self-adjoint operators in Hilbert spaces is the major problem of spectral theory. In this talk I plan to focus on the absolutely continuous part of the spectrum. I am going to review the history of the problem with the main emphasis on 1D Schrödinger operators. If time permits, I will present some new results obtained recently with J. Eckhardt (Vienna/Loughborough) for the class of generalized indefinite strings.
