We demonstrate that provided the Hurst parameter is chosen sufficiently small, this shift allows to establish well-posedness and stability to the corresponding problem - without the need of renormalization - in any dimension. We moreover provide a robustified Feynman-Kac type formula for the unique solution to the regularized problem building upon regularity estimates for the local time of fractional Brownian motion as well as non-linear Young integration.", "revisions": [ { "version": "v1", "updated": "2022-05-10T10:32:21.000Z" } ], "analyses": { "keywords": [ "arbitrary dimension", "random translation", "continuous pam", "related models", "fractional brownian motion" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
