We give necessary and sufficient conditions for the occurrence of eigenvalues of the Schrodinger operator in strips and cylinders under small localized perturbations. We construct asymptotic approximations for the eigenvalues.
Keywords: Schrodinger operator, waveguide, spectrum, asymptotic approximation.
Mots-clés : perturbation
