Numerics of stochastic parabolic differential equations with stable finite difference schemes

In the present article, we focus on the numerical approximation of stochastic partial differential equations of It'o type with space-time white noise process, in particular, parabolic equations. For each case of additive and multiplicative noise, the numerical solution of stochastic diffusion equations is approximated using two stochastic finite difference schemes and the stability and consistency conditions of the considered methods are analyzed. Numerical results are given to demonstrate the computational efficiency of the stochastic methods.
