Energy-preserving integrators for stochastic Poisson systems

D. Cohen and G. Dujardin

Abstract
A new class of energy-preserving numerical schemes for stochastic Hamiltonian systems with non-canonical structure matrix (in the Stratonovich sense) is proposed. These numerical integrators are of mean-square order one and also preserve quadratic Casimir functions. In the deterministic setting, our schemes reduce to methods proposed in [2] and [1].
