Domination spaces and factorization of linear and multilinear summing operators

Abstract

It is well known that not every summability property for multilinear operators leads to a factorization theorem. In this paper we undertake a detailed study of factorization schemes for summing linear and nonlinear operators. Our aim is to integrate under the same theory a wide family of classes of mappings for which a Pietsch type factorization theorem holds. Our construction includes the cases of absolutely p-summing linear operators, (p; )-absolutely continuous linear operators, factorable strongly p-summing multilinear operators, (p1; : : : ; pn)-dominated multilinear operators and dominated (p1; : : : ; pn; )-continuous multilinear operators.
