Leap-frog method for stochastic functional wave equations

Henryk Leszczyński , Milena Matusik , Monika Wrzosek


We perform a time-space discretisation, known as the leap-frog method, for nonlinear stochastic functional wave equations driven by multiplicative time-space white noise. To prove its stability we apply Cairoli's maximal inequalities for two-parameter martingales and provide a lemma for estimating solutions to a class of stochastic wave equations and a Gronwall-type inequality over cones. The method converges in L2 at a rate of O(ph)), where h is a time-space step size.
