Second in a series beginning with math.MG/9811071", "categories": [ "math.MG" ], "abstract": "This is the second in a series of papers giving a proof of the Kepler conjecture, which asserts that the density of a packing of congruent spheres in three dimensions is never greater than $\\pi/\\sqrt{18}\\approx 0.74048...$. This is the oldest problem in discrete geometry and is an important part of Hilbert's 18th problem. An example of a packing achieving this density is the face-centered cubic packing. This paper defines a local formulation of the conjecture which is used in the proof.", "revisions": [ { "version": "v2", "updated": "2002-05-20T21:10:05.000Z" } ], "analyses": { "keywords": [ "kepler conjecture", "hilberts 18th problem", "local formulation", "congruent spheres", "important part" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1998math.....11072F" } } }
