Maximal semigroups in semi-simple Lie groups
(Amer Mathematical SocProvidenceEUA, 2001)
Weak type (1,1) estimates for Caffarelli-Calderón generalized maximal operators for semigroups associated with Bessel and Laguerre operators
(American Mathematical Society, 2014-01)
In this paper we prove that the generalized (in the sense of Caffarelli and Calderón) maximal operators associated with heat semigroups for Bessel and Laguerre operators are weak type $ (1,1)$. Our results include other ...
Weighted norm inequalities for heat-diffusion Laguerre's semigroups
(Springer, 2007-10)
We consider three systems of Laguerre functions and their corresponding heat diffusion semigroups. For the associate maximal operators, we give necessary and sufficient conditions in order to obtain strong type, weak type ...

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 ...
Local maximal functions and operators associated to Laguerre expansions
(Tohoku University, 2014-07)
In this paper we get sharp conditions on a weight v which allow us to obtain some weighted inequalities for a local Hardy-Littlewood Maximal operator defined on an open set in the Euclidean n-space. This result is applied ...
BMO spaces related to Laguerre semigroups
(Wiley, 2014-08)
For the system of Laguerre functions inline image we define a suitable BMO space from the atomic version of the Hardy space inline image considered by Dziubański in [7], where inline image is the maximal operator of the ...
