Spectral and scattering theory for perturbed block Toeplitz operators
Petru Cojuhari, Jaouad Sahbani
We analyse spectral properties of a class of compact perturbations of block Toeplitz operators associated with analytic symbols. In particular, a limiting absorption principle and…

Spectral theory of a class of Block Jacobi matrices and applications
Jaouad Sahbani
We develop a spectral analysis of a class of block Jacobi operators based on the conjugate operator method of Mourre. We give several applications including scalar Jacobi operators…
