Weak type estimates for singular integrals related to a dual problem of Muckenhoupt-Wheeden
(Birkhäuser Publishing, 2009)
Weighted norm inequalities for vector-valued singular integrals on homogeneous spaces
(Polish Acad Sciences Inst MathematicsWarsawPolónia, 2004)
Hörmander conditions for vector-valued kernels of singular integrals and their commutators
(Unión Matemática Argentina, 2019-06)
We study Coifman type estimates and weighted norm inequalities for singular integral operators and their commutators, given by the convolution with a vector-valued kernel. We define a weaker Hörmander type condition ...
Mixed estimates for singular integrals on weighted Hardy spaces
(Universidad Complutense de Madrid, 2019-11)
In this paper we give quantitative bounds for the norms of different kinds of singular integral operators on weighted Hardy spaces $H_w^p$, where $0
Análisis armónico asociado a problemas espectrales para operadores de tipo diferenciación fraccionaria en espacios métricos con medida
(2022-08-05)
En esta tesis abordamos el estudio del análisis espectral del laplaciano fraccionario definido sobre espacios de tipo homogéneo. En primer lugar estudiamos en detalle las propiedades de cierta clase de espacios de Sobolev, ...
Sparse and weighted estimates for generalized Hörmander operators and commutators
(Springer Wien, 2020-01-07)
In this paper a pointwise sparse domination for generalized Hörmander and also for iterated commutators with those operators is provided generalizing the sparse domination result in Lerner et al. (Adv Math 319:153–181, ...
Vector-valued operators, optimal weighted estimates and the Cp condition
(Springer, 2020-07)
In this paper some new results concerning the Cp classes introduced by Muckenhoupt (1981) and later extended by Sawyer (1983), are provided. In particular, we extend the result to the full expected range p < 0, to the weak ...
