Littlewood-Paley functions associated with general Ornstein-Uhlenbeck semigroups

In this paper we establish Lp(Rd, γ∞)-boundedness properties for square functions involving time and spatial derivatives of Ornstein-Uhlenbeck semigroups. Here γ∞ denotes the invariant measure. In order to prove the strong type results for 1 < p < ∞ we use R-boundedness. The weak type (1,1) pr...

Sumario:In this paper we establish Lp(Rd, γ∞)-boundedness properties for square functions involving time and spatial derivatives of Ornstein-Uhlenbeck semigroups. Here γ∞ denotes the invariant measure. In order to prove the strong type results for 1 < p < ∞ we use R-boundedness. The weak type (1,1) property is established by studying separately global and local operators defined for the square Littlewood-Paley functions. By the way we prove Lp(Rd, γ∞)-boundedness properties for maximal and variation operators for Ornstein-Uhlenbeck semigroups.
