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.
