Sharp $$A_{1}$$A1 Weighted Estimates for Vector-Valued Operators

Abstract

Given 1 ≤ q < p < ∞, quantitative weighted L p estimates, in terms of Aq weights, for vector-valued maximal functions, Calderón–Zygmund operators, commutators, and maximal rough singular integrals are obtained. The results for singular operators will rely upon suitable convex body domination results, which in the case of commutators will be provided in this work, obtaining as a byproduct a new proof for the scalar case as well.
