Green matrix estimates of block Jacobi matrices I: Unbounded gap in the essential spectrum

Jan Janas, Sergey Naboko, Luis O. Silva

This work deals with decay bounds for Green matrices and generalized eigenvectors of block Jacobi matrices when the real part of the spectral parameter lies in an infinite gap of t…
