Approximation for semilinear stochastic evolution equations

We investigate the approximation by space and time discretization of quasi linear evolution equations driven by nuclear or space time white noise. An error bound for the implicit Euler, the explicit Euler, and the Crank-Nicholson scheme is given and the stability of the schemes are considered. Lastly we give some examples of different space approximation, i.e., we consider approximation by eigenfunction, finite differences and wavelets.
