In addition to being interesting in its own right, we argue that the resulting diffusion process is a natural hard edge counterpart to the Ferrari-Spohn diffusion of arXiv:math/0308242. In particular, we show that the generator of our new diffusion has the same relation to the Sturm-Liouville problem for the Bessel operator that the Ferrari-Spohn diffusion does to the corresponding problem for the Airy operator.", "revisions": [ { "version": "v1", "updated": "2023-07-12T23:53:54.000Z" } ], "analyses": { "subjects": [ "60J60", "34B24" ], "keywords": [ "ferrari-spohn diffusion", "bounded bessel processes", "natural hard edge counterpart", "airy operator", "bessel operator" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
