Abstract

We prove quantitative bounds on the eigenvalues of non-selfadjoint unbounded
operators obtained from selfadjoint operators by a perturbation that is
relatively-Schatten. These bounds are applied to obtain new results on the
distribution of eigenvalues of Schroedinger operators with complex potentials.
