Abstract

For each p in [1, ∞) let Ep denote the closure of the region of holomorphy of the Ornstein-Uhlenbeck semigroup {ℋt: t > 0} on Lp with respect to the Gaussian measure. Sharp weak type and strong type estimates are proved for the maximal operator f ℋp*f = sup{ℋ zf |: z ∈ Ep} and for a class of related operators. As a consequence, a new and simpler proof of the weak type 1 estimate is given for the maximal operator associated to the Mehler kernel.
