Let + be a nondegenerate Gaussian measure on a Hilbert space H. For an arbitrary selfadjoint nonnegative operator A we consider the semigroup e tL = 1(e &tA ) on L p (+), where 1 stands for the second quantization operator. We provide an explicit characterization of the domains of (I&L) mร2 in L p (

โฆ Synopsis
By using the LITTLEWOOD matrices B g n we generalize CLAEKSON'S inequelitiee, or equivalently, we determine the norms IIAzn : Z,2"(Lp) + Zr(Lp)ll completely. The result is compared with the norms IIAp : 1,2" -+ Zrl l , which are calculated implicitly in PIETSOE [el.

We show that transport inequalities, similar to the one derived by M. Talagrand (1996, Geom. Funct. Anal. 6, 587 600) for the Gaussian measure, are implied by logarithmic Sobolev inequalities. Conversely, Talagrand's inequality implies a logarithmic Sobolev inequality if the density of the measure i
