Nonlinear stochastic differential inclusions on balance space

In this paper we present some new results on the existence and regularity of mild solutions of a class of nonlinear stochastic differential inclusions on Hilbert space. The drift is multivalued and the diffusion is single valued but both nonlinear admitting differential operators unlike in [3]. The drift term contains a generator of a C 0 analytic semigroup in addition to the multivalued drift
