On the approximation for singularly perturbed stochastic wave equations

We explore the relation between fast waves, damping and imposed noise for different scalings by considering the singularly perturbed stochastic nonlinear wave equations �utt +ut = �u +f(u) +� � u W on a bounded spatial domain. An asymptotic approximation to the stochastic wave equation is constructed by a special transformation and
