OSCILLATION AND VARIATION OF THE LAGUERRE HEAT AND POISSON SEMIGROUPS AND RIESZ TRANSFORMS

In this article,we study Lp-boundedness properties of the oscillation and variation operators for the heat and Poissson semigroup and Riesz transforms in the Laguerre settings.Also,we characterize Hardy spaces associated to Laguerre operators by using the variation operator of the heat semigroup.
