Approximate solutions for stochastic time‐fractional reaction–diffusion equations with multiplicative noise

In this paper, we consider the approximate solutions of time‐fractional reaction–diffusion equations forced by multiplicative noise on a bounded domain. When the diffusion is large, one can approximate the solutions of the stochastic time‐fractional reaction–diffusion equations with polynomial term by the solutions of a stochastic time‐fractional ordinary equations. We illustrate our results by applying to time‐fractional logistic and time‐fractional Ginzburg–Landau equations.
