We show that any centrally symmetric or pseudo-symmetric smooth Fano polytopes can be obtained from directed graphs. Moreover, by using directed graphs, we provide new examples of smooth Fano polytopes whose corresponding varieties admit K\\\"ahler--Einstein metrics.", "revisions": [ { "version": "v4", "updated": "2014-06-30T07:10:28.000Z" } ], "analyses": { "subjects": [ "14M25", "52B20", "05C20" ], "keywords": [ "smooth fano polytopes arising", "finite directed graphs", "graphs yield smooth fano polytopes", "pseudo-symmetric smooth fano polytopes", "directed graphs yield smooth fano" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.2202H" } } }
