Abstract
We consider the stochastic evolution equation on a Hilbert space H written formally as dXt= A(t)Xt dt + dZ(X)t t∈[0,T], where {A(t),∈[Q,T]} is a family of infinitesimal generations of Co-semigroups on H and Z(X) is a semimartingale with values in H which may depend on the process X. We define several types of solutions of this equation, under the assumption that ∩∈[o,T]D(*(t))is dense in H. The main purpose of this paper is to investigate relationships among these solutions
