Perturbation determinants and discrete spectra of semi-infinite non-self-adjoint Jacobi operators

Spectral Theory 2021-08-11 v2 Functional Analysis

Abstract

We study the trace class perturbations of the half-line, discrete Laplacian and obtain a new bound for the perturbation determinant of the corresponding non-self-adjoint Jacobi operator. Based on this bound, we obtain the Lieb--Thirring inequalities for such operators. The spectral enclosure for the discrete spectrum and embedded eigenvalues are also discussed.
