Abstract

We consider the modified Crank-Nicholson difference schemes for the approximate solution of the initial value Cauchy problem for stochastic parabolic equation [image omitted] in a Hilbert space H with the self-adjoint positive definite operator A. Here: (1) wt is a standard Wiener process given on the probability space (Ω,F,P). (2) f(t) is an element of space [image omitted] that consists of H1-value processes for which the condition [image omitted] is satisfied. The estimate of convergence for the solution of these difference schemes is obtained.
