题目: Gevrey estimates of the resolvent and sub-exponential time-decay of solutions


报告人:王雪平(University of Nantes, France)


摘要:  Spectral analysis of non-selfadjoint Schrödinger operators is a topic related to several branches of mathematics. In this talk, we study a class of non-selfadjoint Schrödinger operators which are compactly supported perturbation of some model operator verifying a weighted coercive condition. We establish large-time expansion of solutions to the time-dependent Schrödinger equation with sub-exponential time-decay estimate on the remainder, including the case of zero eigenvalue and positive resonances.
