Mixed inequalities of Fefferman-Stein type for singular integral operators

Fabio Berra, Marilina Carena, Gladis Pradolini

We give Feffermain-Stein type inequalities related to mixed estimates for Calderón-Zygmund operators. More precisely, given $δ > 0$ , $q > 1$ , $φ (z) = z (1 + lo g^{+} z)^{δ}$ , a nonnegative and l…

Mixed inequalities for commutators with multilinear symbol

Fabio Berra, Marilina Carena, Gladis Pradolini

We prove mixed inequalities for commutators of Calderón-Zygmund operators (CZO) with multilinear symbols. Concretely, let $m \in N$ and $b = (b_{1}, b_{2}, \dots, b_{m})$ be…

Improvements on Sawyer type estimates for generalized maximal functions

Fabio Berra, Marilina Carena, Gladis Pradolini

In this paper we prove mixed inequalities for the maximal operator $M_{Φ}$ , for general Young functions $Φ$ with certain additional properties, improving and generalizing some previo…

Mixed weak estimates of Sawyer type for fractional integrals and some related operators

Fabio Berra, Marilina Carena, Gladis Pradolini

We prove mixed weak estimates of Sawyer type for fractional operators. More precisely, let $T$ be either the maximal fractional function $M_{γ}$ or the fractional integral…
