a numerical technique for solving nonlinear fractional stochastic integro-differential equations with n-dimensional wiener process

this paper deals with the numerical solution of nonlinear fractional stochastic integro-differential equations with the n-dimensional wiener process. a new computational method is employed to approximate the solution of the considered problem. this technique is based on the modi ed hat functions, the caputo derivative, and a suitable numerical integration rule. error estimate of the method is investigated in detail. in the end, illustrative examples are included to demonstrate the validity and effectiveness of the presented approach.
