Abstract

Semilinear wave equations with additive or one-dimensional noise are treatable by various iterative and numerical methods. We study more difficult models of semilinear wave equations with infinite dimensional multiplicative spatially correlated noise. Our proof of probabilistic second-order convergence of some iterative methods is based on Da Prato and Zabczyk's maximal inequalities.
