Discrete Besov spaces via semigroups associated to the discrete Laplacian and regularity of non-local operators
Luciano Abadias, Marta De León-Contreras, Alejandro Mahillo
In this paper we prove characterizations of the discrete Besov spaces in terms of the heat and Poisson semigroups associated with the discrete Laplacian that will allow us to prove…
Variation and oscillation for semigroups associated with discrete Jacobi operators
Jorge J. Betancor, Marta De León-Contreras
In this paper we prove weighted -inequalities for variation and oscillation operators defined by semigroups of operators associated with discrete Jacobi operators. Also, we…
Variation inequalities for Riesz transforms and Poisson semigroups associated with Laguerre polynomial expansions
Jorge J. Betancor, Marta De León-Contreras
In this paper we establish -boundedness properties for variation, oscillation and jump operators associated with Riesz transforms and Poisson semigroups related to Laguerre po…
Variation operators for semigroups associated with Fourier-Bessel expansions
Jorge J. Betancor, Alejandro J. Castro, Marta De León-Contreras
In this paper we establish -boundedness properties for variation operators defined by semigroups associated with Fourier-Bessel expansions.
The quasi-static plasmonic problem for polyhedra
Marta de León-Contreras, Karl-Mikael Perfekt
We characterize the essential spectrum of the plasmonic problem for polyhedra in . The description is particularly simple for convex polyhedra and permittivities $ε<…
The Hardy-Littlewood property and maximal operators associated with the inverse Gauss measure
Jorge J. Betancor, Alejandro J. Castro, Marta De León-Contreras
In this paper we characterize the Banach lattices with the Hardy-Littlewood property by using maximal operators defined by semigroups of operators associated with the inverse Gauss…
