Based on the Runge-Kutta--Munthe-Kaas (RKMK) method for ordinary differential equations on Lie groups, we present a stochastic version of this scheme and derive a condition such that the stochastic RKMK has the same strong convergence order as the underlying stochastic Runge-Kutta method. Further, we show how our higher order schemes can be applied in a mechanical engineering as well as in a financial mathematics setting.", "revisions": [ { "version": "v1", "updated": "2021-02-08T11:10:40.000Z" } ], "analyses": { "subjects": [ "60H10", "70G65", "91G80" ], "keywords": [ "matrix lie groups", "strong convergence order", "designing higher strong order methods", "stochastic differential equations", "higher order schemes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
