A novelty appearing here is that we use coordinates for the flow that are indexed by trees rather than multi-indices.", "revisions": [ { "version": "v1", "updated": "2024-11-11T17:34:12.000Z" } ], "analyses": { "keywords": [ "rough differential equations", "flow approach", "rough stochastic differential equations driven", "fractional brownian motion", "elementary differentials" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
