Littlewood-Paley-Stein theory and Banach spaces in the inverse Gaussian setting
V. Almeida, J. J. Betancor, J. C. Fariña +1
In this paper we consider Littlewood-Paley functions defined by the semigroups associated with the operator in the inverse Gaussian setting for Ban…
Discrete Hardy spaces and heat semigroup associated with the discrete Laplacian
Víctor Almeida, Jorge J. Betancor, Lourdes Rodríguez Mesa
In this paper we study the behavior of some harmonic analysis operators associated with the discrete Laplacian in discrete Hardy spaces . We prove th…
Local Hardy spaces with variable exponents associated to non-negative self-adjoint operators satisfying Gaussian estimates
Víctor Almeida, Jorge J. Betancor, Estefanía Dalmasso +1
In this paper we introduce variable exponent local Hardy spaces associated with a non-negative self-adjoint operator L. We define them by using an area square integral involving th…
Molecules associated to Hardy spaces with pointwise variable anisotropy
Víctor Almeida, Jorge J. Betancor, Lourdes Rodríguez-Mesa
In this paper we introduce molecules associated to Hardy spaces with pointwise variable anisotropy, and prove that each molecule can be represented as a sum of atoms.
-boundeness properties of variation operators in the Schrodinger setting
J. J. Betancor, J. C. Fariña, E. Harboure +1
In this paper we establish the -boundedness properties of the variation operators associated with the heat semigroup, Riesz transforms and commutator between Riesz transforms…
Higher Order Riesz Transforms for Laguerre Expansions
Jorge J. Betancor, Juan C. Fariña, Lourdes Rodriguez-Mesa +1
In this paper we investigate Lp-boundedness properties for the higher order Riesz transforms associated with Laguerre operators. Also we prove that the k-th Riesz transform is a pr…
