Abstract:
A support theorem is proven for the mild solution of the stochastic differential equation in a Hilbert space of the form: $$dX(t)=AX(t)dt+b(X(t))dt +\sigma(X(t))dB(t).$$ It is driven by a Hilbert space-valued Wiener process $B$, with the infinitesimal generator $A$ of a ($C_0$)-semigroup.
