We deduce this bound as a consequence of a strong Cayley decomposition theorem which says, roughly speaking, that any lattice polytope with a large multiple that has no interior lattice points has a nontrivial decomposition as a Cayley sum of polytopes of smaller dimension. In an appendix, we interpret this result in terms of adjunction theory for toric varieties.", "revisions": [ { "version": "v1", "updated": "2008-04-23T09:15:11.000Z" } ], "analyses": { "subjects": [ "52B20", "14M25", "14C20" ], "keywords": [ "lattice polytope", "strong cayley decomposition theorem", "interior lattice points", "large multiple", "effective upper bound" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0804.3667H" } } }
