In the case of nonalternating knots, some semi-alternating knots or links have this property. We mainly focus on the problem of mutation invariance of the arc index for nonalternating knots which are not semi-alternating. In this paper, we found families of infinitely many mutant pairs/triples of Montesinos knots with the same arc index.", "revisions": [ { "version": "v1", "updated": "2017-04-06T11:32:10.000Z" } ], "analyses": { "subjects": [ "57M25", "57M27" ], "keywords": [ "arc index", "montesinos knots", "mutation invariance", "nonalternating knots", "mutant pairs/triples" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
