Abstract
Let be two separable Hilbert spaces. The main goal of this paper is to study the weak uniqueness of the Stochastic Differential Equation evolving in \begin{align*} dX(t)=AX(t)dt+\mathcal{V}B(X(t))dt+GdW(t), \quad t>0, \quad X(0)=x \in H, \end{align*} where is a -cylindrical Wiener process, is the infinitesimal generator of a strongly continuous semigroup, are linear bounded operators and is a uniformly continuous function. The abstract result in this paper gives the weak uniqueness for large classes of heat and damped equations in any dimension without any H\"older continuity assumption on .
