An upper bound for the number of eigenvalues of non-selfadjoint Schrödinger operator
S. A. Stepin
Estimates for the total multiplicity of eigenvalues for Schrödinger operator are established in the case of compactly supported or exponentially decreasing complex-valued potential…

Scattering and bound states for nonselfadjoint Schrödinger operator
S. A. Stepin
Spectral components of one-dimensional Schrödinger operator with complex potential are investigated. An effective upper bound for the total number of eigenvalues and spectral singu…
