                An operatorial approach to stochastic infinite differential equations.

Abstract.            

 This is a joint work with Michael Röckner (Bielefeld). The stochastic differential equation
$dX + A(t) X dt = XdW $ where $A(t)$ is a monotone demicontinuous and
coercive operator from in a duality pair $V,V'$ can be reduced to an
operatorial equation  $ By + \val A y=0$ where $B$ and $\cal A$ are
maximal monotone operators in certain dual pair of Banach spaces $\cal
V, \cal V '$ of adapted processes from $V$ to $V'.$ In this way
existence reduces to standard existence results in theory of maximal
monotone operators. This functional scheme covers most of stochastic
PDEs in the literature.
