Discrete spectrum and resonances of a one-dimensional Schrödinger operator for small values of the coupling constants

S. N. Lakaev


Abstract: Expansions into powers of a small coupling constant are derived for the eigen-value and resonance of one-dimensional Schrödinger operator. Character of changes of the number of eigen-values is studied and the formulas for the number of negative eigenvalues are pointed out.
