Maximal operators related to the Ornstein-Uhlenbeck semigroup with complex time parameter
Artikel i vetenskaplig tidskrift, 2006

Let γ be the Gaussian measure in Click to view the MathML source and Click to view the MathML source, t>0, the corresponding Ornstein-Uhlenbeck semigroup, whose infinitesimal generator is Click to view the MathML source. For each p with 12 this operator is of weak type but not of strong type (p,p) for γ. However, if a neighbourhood of the origin is deleted from Ep in the definition of Click to view the MathML source, the resulting operator is shown to be of strong type.
