We present new integral identities, that show a strong analogy between the two problems and help to obtain better (in some cases optimal) quantitative estimates for the radially symmetric configuration. The estimates for the Soap Bubble Theorem benefit from those of Serrin's problem.", "revisions": [ { "version": "v1", "updated": "2017-08-24T13:25:43.000Z" } ], "analyses": { "subjects": [ "35N25", "53A10", "35B35", "35A23" ], "keywords": [ "alexandrovs soap bubble theorem", "serrins problem", "integral identities", "enhanced stability", "soap bubble theorem benefit" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
