That extra term must be included in the stochastic integration. This yields the Ito sense of the SDE, while the FPE belongs to the anti-Ito sense and preserves important features of the case with a constant diffusion. An existing inconsistency is thereby removed.", "revisions": [ { "version": "v1", "updated": "2015-10-05T17:19:47.000Z" } ], "analyses": { "subjects": [ "60H10" ], "keywords": [ "stochastic differential equations", "preserves important features", "extra term", "fokker-planck equation", "constant diffusion" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
