Abstract

We prove the existence and uniqueness of the solution to a variable-order fractional stochastic differential equation driven by a multiplicative white noise, which describes the random phenomena with nonlocal effect. We further develop a Euler-Maruyama scheme and prove the strong convergence of the scheme. Numerical experiments are presented to substantiate the mathematical analysis.
