The discrete spectrum for complex perturbations of periodic Jacobi matrices

I. Egorova, L. Golinskii

We study spectrum inclusion regions for complex Jacobi matrices which are compact perturbations of real periodic Jacobi matrices. The condition sufficient for the lack of discrete…

On limit sets for the discrete spectrum of complex Jacobi matrices

I. Egorova, L. Golinskii

The discrete spectrum of complex Jacobi matrices that are compact perturbations of the discrete laplacian is under consideration. The rate of stabilization for the the matrix entri…
