Spectral stability of Schrödinger operators with subordinated complex potentials
(Journal of Spectral Theory, 2018-06-28)We prove that the spectrum of Schroedinger operators in three dimensions is purely continuous and coincides with the non-negative semiaxis for all potentials satisfying a form-subordinate smallness condition. By developing ...
