Doubling and weighting the edges of the graph produces a second Laplacian matrix such that a principal minor is an Alexander matrix of the link. The Goeritz matrix and signature invariants are obtained in a similar way. A device introduced by L. Kauffman makes it possible to apply the method to general diagrams.", "revisions": [ { "version": "v1", "updated": "2018-09-18T00:45:44.000Z" } ], "analyses": { "subjects": [ "57M25", "57M15" ], "keywords": [ "knot invariants", "principal minor", "second laplacian matrix", "goeritz matrix", "similar way" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
