On Riesz transforms and maximal functions in the context of Gaussian harmonic analysis
(American Mathematical Society, 2007-12)
The purpose of this paper is twofold. We introduce a general maximal function on the Gaussian setting which dominates the Ornstein-Uhlenbeck maximal operator and prove its weak type by using a covering lemma which is ...
Pointwise estimates for gradients of temperatures in terms of maximal functions
(Unión Matemática Argentina, 2009-12)
We give a detailed proof, in the case of one space dimension, of a pointwise upper estimate for the space gradient of a temperature. The operators involved are a one-sided maximal Hardy-Littlewood in time and the Calderón ...
Maximal operators associated with Generalized Hermite polynomials and function expansions
(Union Matematica Argentina, 2013-06)
We study the weak and strong type boundedness of maximal heat?diffusion operators associated with the system of generalized Hermite polynomials and with two different systems of generalized Hermite functions. We also give ...
Generalized maximal functions and related operators on weighted Musielak-Orlicz spaces
(Suomalainen Tiedeakatemia, 2014-02)
We characterize the class of weights related to the boundedness of maximal operators associated to a Young function η in the context of variable Lebesgue spaces. Fractional versions of these results are also obtained by ...
Characterizations of the boundedness of generalized fractional maximal functions and related operators in Orlicz spaces
(Wiley VCH Verlag, 2017-01)
Given 0 <α< n and a Young function η, we consider the generalized fractional maximal operator Mα,η defined by Mα,η f (x) = sup Bx |B| α/n || f ||η,B, where the supremum is taken over every ball B contained in Rn . In this ...
THE MAXIMAL ENTROPY MEASURE DETECTS NON-UNIFORM HYPERBOLICITY
(INT PRESS BOSTON, INC, 2010)
We characterize two of the most studied non-uniform hyperbolicity conditions for rational maps, semi-hyperbolicity and the topological Collet-Eckmann condition, in terms of the maximal entropy measure.
Boundedness of the Hardy–Littlewood Maximal Operator Along the Orbits of Contractive Similitudes
(Springer, 2012-03)
In this note we obtain results regarding the preservation of homogeneity properties along the whole orbit of a given iterated function system (IFS). We have essentially two types of results. The first class of them contains ...
On the maximal function for the generalized Ornstein-Uhlenbeck semigroup
(Natl Inquiry Services Centre Pty Ltd, 2007-12)
In this note we consider the maximal function for the generalized Ornstein-Uhlenbeck semigroup in R associated with the generalized Hermite polynomials (Hμn) and prove that it is weak type (1,1) with respect to dλμ(x) = ...
