As applications, we determine the dealternating numbers, the alternation numbers and the Turaev genera of some closed positive 3-braids. We also show that there exist infinitely many positive knots with any dealternating number (or any alternation number) and any braid index.", "revisions": [ { "version": "v2", "updated": "2008-12-10T19:22:35.000Z" } ], "analyses": { "subjects": [ "57M25" ], "keywords": [ "dealternating number", "alternation number", "upper bound", "turaev genera" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0808.0573A" } } }
