Stochastic B-series and order conditions for exponential integrators

Numerical Analysis 2019-07-18 v1

Abstract

We discuss stochastic differential equations with a stiff linear part and their approximation by stochastic exponential integrators. Representing the exact and approximate solutions using B-series and rooted trees, we derive the order conditions for stochastic exponential integrators. The resulting general order theory covers both It\^{o} and Stratonovich integration.
