This result also shows that the answer to the open problem raised by Gehring, Hag and Martio in \\cite{Gm} is positive for John domains which are homeomorphic to uniform domains via uasiconformal mappings. As an application, we prove that if $D\\subset R^n$ is a John domain which is homeomorphic to a uniform domain, then $D$ must be a quasihyperbolic $(b, \\lambda)$-uniform domain.", "revisions": [ { "version": "v1", "updated": "2011-04-27T12:44:38.000Z" } ], "analyses": { "subjects": [ "30C65", "30F45", "30C20" ], "keywords": [ "john domain", "quasihyperbolic geodesic", "uniform domain", "homeomorphic", "cone arc" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1104.5128H" } } }
