Christiane Tretter: Spectral inclusions for operators with spectral gaps
Time: Wed 2015-06-10 11.00 - 12.00
Location: Room 306, House 6, Kräftriket, Department of Mathematics, Stockholm University
Participating: Christiane Tretter, Department of Mathematics, University of Bern
In this talk relatively bounded, not necessarily symmetric perturbations of selfadjoint operators with spectral gap are considered. We present new spectral inclusion results and various modifications e.g. for gaps of the essential spectrum or for infinitely many gaps.
