Numerical Solution of a Model for Stochastic Polymer Equation Driven by Space–Time Brownian Motion via Homotopy Perturbation Method

The goal of this paper is to give useful method for solving a problem in polymer that is formulated by stochastic mixedVolterra–Fredholm integral equations driven by space–time white noise.Here, we consider homotopy perturbationmethod which consists in constructing the series whose sum is the solution of the considered problem. The method is applied to test examples to illustrate the accuracy and implementation of it. The results reveal that the proposed method is very effective.
