Perturbation of Schrödinger operator by slender potential. (Russian. English summary) Zbl 1249.35069
Summary: A discrete spectrum of the Schrödinger operator perturbed by a potential on the real line is studied. The potential depends on two small parameters. One of the parameters describes the length of the support of the potential and the inverse of the other parameter corresponds to the magnitude of the potential.
