Abstract

We investigate the strong approximation of stochastic parabolic partial differential equations with additive noise. We introduce post-processing in the context of a standard Galerkin approximation, although other spatial discretisations are possible. In time, we use an exponential integrator. We prove strong error estimates and discuss the best number of post-processing terms to take. Numerically, we evaluate the efficiency of the methods and observe rates of convergence. Some experiments with the implicit Euler--Maruyama method are described
