After providing a linking construction for hyperconvex spaces, we show that the four-point property is inherited by the hyperconvex hull, which leads to the theorem that every complete metric tree is hyperconvex. We also consider some extension theorems for these spaces.", "revisions": [ { "version": "v1", "updated": "2007-02-05T22:27:09.000Z" } ], "analyses": { "subjects": [ "54H12", "46M10" ], "keywords": [ "hyperconvexity", "hyperconvex hull", "complete metric tree", "hyperconvex spaces", "four-point property" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007math......2125A" } } }
