Schrödinger operators with slowly decaying potentials. (English) Zbl 1019.34083
Summary: Several recent papers have obtained bounds on the distribution of eigenvalues of nonselfadjoint Schrödinger operators and resonances of selfadjoint operators. Here, the authors describe two new methods of obtaining such bounds when the potential decays more slowly than previously permitted.
