Quantitative weighted estimates for harmonic analysis operators in the Bessel setting by using sparse domination
Víctor Almeida, Jorge J. Betancor, Juan C. Fariña +1
In this paper we obtain quantitative weighted -inequalities for some operators involving Bessel convolutions. We consider maximal operators, Littlewood-Paley functions and var…
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 associated with the semigroups generated by Schrödinger operators with inverse square potentials
Víctor Almeida, Jorge J. Betancor, Lourdes Rodríguez-Mesa
By we denote the semigroup of operators generated by the Friedrichs extension of the Schrödinger operator with the inverse square potential $L_a=-Δ+\frac{a}{|x|^2…
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.
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…
