Homotopy Analysis Method for Stochastic Differential Equations with Maxima

The homotopy analysis method known from its successful applications to obtain quasi-analytical approximations of solutions of ordinary and partial differential equations is applied to stochastic differential equations with Gaussian stochastic forces. It has been found that the homotopy analysis method yields excellent agreement with exact results (when the latter are available) and appears to be a very promising approach in the calculations related to quantum field theory and quantum statistical mechanics. Using a computer algebra system Maxima has considerably influnced and simplified the calculations and results.
