Abstract
We study factorization of operators between quasi-Banach spaces. We prove the equivalence between certain vector norm inequalities and the factorization of operators through Orlicz spaces. As a consequence, we obtain the Maurey–Rosenthal factorization of operators into \(L_p\)-spaces. We give several applications. In particular, we prove a variant of Maurey’s Extension Theorem.
