Asymptotics for eigenvalues of Schrödinger operator with small shift and Dirichlet condition

We consider a non-self-adjoint Schrödinger operator on the unit segment with the Dirichlet condition perturbed by an operator of small translation. The main result is the three-terms asymptotics for the eigenvalues with respect to their index and this asymptotics is uniform in the small translation. We also show that the system of eigenfunctions and associated functions of the considered operators forms a Bari basis in the space of functions square integrable on the considered unit segment.

Abstract

We consider a non-self-adjoint Schrödinger operator on the unit segment with the Dirichlet condition perturbed by an operator of small translation. The main result is the three-terms asymptotics for the eigenvalues with respect to their index and this asymptotics is uniform in the small translation. We also show that the system of eigenfunctions and associated functions of the considered operators forms a Bari basis in the space of functions square integrable on the considered unit segment.
