Query: A Maximum Principle for Optimal Control of Stochastic Evolution
  Equations   A general maximum principle is proved for optimal controls of abstract
semilinear stochastic evolution equations. The control variable, as well as
linear unbounded operators, acts in both drift and diffusion terms, and the
control set need not be convex.
