Abstract.We study the realization of the differential operator
$$u mapsto u_t - L(t)u$$
in the space of continuous time periodic functions, and in L2 with respect to its (unique) invariant measure. Here L(t) is an Ornstein-Uhlenbeck operator in $${mathbb{R}}^n$$
, such that L(t + T) = L(t) for each
$$t in {mathbb{R}}$$
.
