Uniform Sobolev estimates for Schrödinger operators with scaling-critical potentials and applications

Haruya Mizutani

Vol. 13 (2020), No. 5, 1333–1369
Abstract

We prove uniform Sobolev estimates for the resolvent of Schrödinger operators with large scaling-critical potentials without any repulsive condition. As applications, global-in-time Strichartz estimates including some nonadmissible retarded estimates, a Hörmander-type spectral multiplier theorem, and Keller-type eigenvalue bounds with complex-valued potentials are also obtained.
