A discrete-time counterpart of such a semigroup, the proximal point algorithm, turns out to have the same asymptotic behavior. This complements several results in the literature -- both classical and more recent ones. As an application, we obtain a new approach to heat flows in singular spaces for discrete, as well as continuous times.", "revisions": [ { "version": "v2", "updated": "2014-07-24T17:27:26.000Z" } ], "analyses": { "subjects": [ "47H20", "60J45" ], "keywords": [ "asymptotic behavior", "hadamard space", "proximal point algorithm", "discrete-time counterpart", "singular spaces" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1405.6637B" } } }
