![]() Hardy-Littlewood inequalities for norms of positive operators on sequence spaces
(Elsevier, 2013)
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. |
