On pointwise and weighted estimates for commutators of Calderón–Zygmund operators
(Academic Press Inc Elsevier Science, 2017-10)
In recent years, it has been well understood that a Calderón–Zygmund operator T is pointwise controlled by a finite number of dyadic operators of a very simple structure (called the sparse operators). We obtain a similar ...
Multilinear Marcinkiewicz-Zygmund inequalities
(Birkhauser Boston Inc, 2017-09-12)
We extend to the multilinear setting classical inequalities of Marcinkiewicz and Zygmund on (Formula presented.)-valued extensions of linear operators. We show that for certain (Formula presented.), there is a constant ...
End-point estimates for iterated commutators of multilinear singular integrals
(Wiley, 2013-09)
Iterated commutators of multilinear Calderón-Zygmund operators and pointwise multiplication with functions in BMO are studied in products of Lebesgue spaces. Both strong type and weak end-point estimates are obtained, ...
Weighted inequalities for some integral operators with rough kernels
(Versita, 2014-04)
In this paper we study integral operators with kernels $$K(x,y) = k_1 (x - A_1 y) \cdots k_m \left( {x - A_m y} \right),$$ $$k_i \left( x \right) = {{\Omega _i \left( x \right)} \mathord{\left/ {\vphantom {{\Omega _i \left( ...

Multilinear Cesàro maximal operators
(Elsevier Inc, 2012-07)
The study of the almost everywhere convergence of the product of m Cesàro-α averages leads to the characterization of the boundedness of the associated multi(sub)linear maximal operator. We characterize weighted weak type ...
Weighted inequalities related to a Muckenhoupt and Wheeden problem for one-side singular integrals
(Element, 2015-07)
In this paper we obtain for $T^+$, a one-sided singular integral given by a Calder´on-Zygmund kernel with support in $(-infty,0)$, a $L^p(w)$ bound when $win A_1^+$. A. K. Lerner, S. Ombrosi, and C. Pérez in ``$A_{1}$ ...
