dc.description.abstractLet U be a unitary operator defined on a separable infinite-dimensional complex Hilbert space H. Under suitable positivity and regularity assumptions, expressed in terms of higher order commutators, we prove the existence of some Limiting Absorption Principle for powers of the resolvent of U. Consequently, we obtain some decay estimates for the corresponding time discrete evolution on some weighted spaces. We also derive the existence and completeness of some associated local wave operators. Applications include CMV matrices and unitary quantum walks. Keywords: resolvent smoothness, dispersive estimates, commutator, unitary operator, wave operators.es_CL
