Stochastic collocation methods for differential equations with white noiseic collocation methods do not work when longer time integration is required. Though these methods are also cursed by the dimensionality, we apply the recursive strategy for longer time integration discussed in Chapter . to investigate the error behavior of stochastic collocation methods in one-time step approximation or short time integration.

Comparison between Wiener chaos methods and stochastic collocation methodsM). In this chapter, we will compare both methods for . stochastic advection-reaction-diffusion equations with commutative and noncommutative noises. To make a fair comparison, we develop a recursive multistage SCM using a spectral truncation of Brownian motion as in the case of WCE.

Multiplicative white noise: The Wick-Malliavin approximation for elliptic equations with lognormal coefficients and use the Wick product for elliptic equations with spatial white noise as coefficients. Numerical results demonstrate that high-order Wick-Malliavin approximation is efficient even when the noise intensity is relatively large.

Epiloguelo methods have been made in recent years, it is still desirable to have further accelerated sampling techniques. Depending on the specific problem, the integration in random space can be made effective using different methods such as quasi-Monte Carlo methods, Wiener chaos methods, and stochastic collocation methods.

Balanced numerical schemes for SDEs with non-Lipschitz coefficientsal balanced scheme, which is explicit and of half-order mean-square convergence. Some numerical results are presented in Chapter .. We summarize the chapter in Chapter . and present some bibliographic notes on numerical schemes for nonlinear SODEs. Three exercises are presented for interested readers.
