Weighted Local BMO Spaces and the Local Hardy-Littlewood Maximal Operator
(Unión Matemática Argentina, 2011-10)
The purpose of this work is to investigate the behavior of the Local MaximalOperator on appropriate weighted BMO spaces. We believe that ourresult (see theorem below) is new even in the unweighted case.
Riesz transforms related to Schrödinger operators acting on BMO type spaces
(Academic Press Inc Elsevier Science, 2009-09)
In this work we obtain boundedness on suitable weighted BMO type spaces of Riesz transforms, and their adjoints, associated to the Schrödinger operator - Δ + V, where V satisfies a reverse Hölder inequality. Our results ...
A note on generalized Fujii-Wilson conditions and BMO spaces
(Springer, 2020-07-07)
In this note we generalize the definition of the Fujii-Wilson condition providing quantitative characterizations of some interesting classes of weights, such as A∞, A weak∞ and Cp, in terms of BMO type spaces suited to ...
Weighted Lebesgue and $BMO^\gamma $; norm inequalities for the Calderón and Hilbert operators
(Springer, 2019-04)
Necessary and sufficient conditions are given for generalized Calderón and Hilbert operators to be bounded from weighted Lebesgue spaces into suitable weighted BMO and Lipschitz spaces. Moreover, we have obtained new results ...
The fractional integral between Orlicz and BMO(phi) spaces on spaces of homogeneous type
(Faculty of Mathematics and Physics of Charles University, 2003-07)
In this work we give sufficient and necessary conditions for the boundednessof the fractional integral operator acting between weighted Orlicz spaces and suitableBMOφ spaces, in the general setting of spaces of homogeneous ...
Characterization of bmo using wavelets through triebellizorkin spaces
(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2019)
Wavelet expansions for weighted, vector-valued BMO functions
(Springer, 2010-03)
We introduce a scale of weighted Carleson norms, which depend on an integrability parameter p, where p = 2 corresponds to the classical Carleson measure condition. Relations between the weighted BMO norm of a vector-valued ...
Maximal operators, Riesz transforms and Littlewood–Paley functions associated with Bessel operators on BMO
(Academic Press Inc Elsevier Science, 2010-03)
In this paper we study boundedness properties of certain harmonic analysis operators (maximal operators for heat and Poisson semigroups, Riesz transforms and Littlewood–Paley g-functions) associated with Bessel operators, ...

(Elsevier Science, 2010-03)
In this paper we study boundedness properties of certain harmonic analysis operators (maximal operators for heat and Poisson semigroups, Riesz transforms and Littlewood– Paley g-functions) associated with Bessel operators, ...
Characterizations of BMO f ( w )
(Akadémiai Kiadó, 2004-12)
Abstract. In this paper we give two characterizations of func-tions with weighted mean oscillation over cubes controlled by anon-negative function ´, that is functions in BMO´(w). The ¯rstone, by conditions on their ...
