Abstract: It is well-known for self-adjoint Jacobi operators that their absolute continuity and the absolute continuous spectrum in a subset of the real line can be characterized by non-existence of subordinate generalized eigenvectors. In our work we extended the result for block Jacobi operators with singular hopping matrices.
