The sharp weighted maximal inequalities for noncommutative martingales

Operator Algebras 2022-11-18 v1

Abstract

The purpose of the paper is to establish weighted maximal LpL_p-inequalities in the context of operator-valued martingales on semifinite von Neumann algebras. The main emphasis is put on the optimal dependence of the LpL_p constants on the characteristic of the weight involved. As applications, we establish weighted estimates for the noncommutative version of Hardy-Littlewood maximal operator and weighted bounds for noncommutative maximal truncations of a wide class of singular integrals.
