This is an announcement for the paper "Hardy-Littlewood inequalities for norms of positive operators on sequence spaces" by Miguel Lacruz.

Abstract: We consider estimates of Hardy and Littlewood for norms of operators on sequence spaces, and we apply a factorization result of Maurey to obtain improved estimates and simplified proofs for the special case of a positive operator.
