On S-matrix of Schrodinger Operators with Non-Symmetric Zero-Range Potentials
P. A. Cojuhari, A. Grod, S. Kuzhel
Non-self-adjoint Schrodinger operators which correspond to non-symmetric zero-range potentials are investigated. We show that various properties of these operators (eigenvalues, ex…

Schrodinger Operators with Non-Symmetric Zero-Range Potentials
A. Grod, S. Kuzhel
Non-self-adjoint Schrodinger operators A which correspond to non-symmetric zero-range potentials are investigated. For a given A, the description of non-real eigenvalues, spectral…
