Moreover, we give a rational surgery formula for the unified invariant dominating WRT SO(3) invariants of rational homology 3-spheres at roots of unity of order co-prime with the torsion. As an application, we compute the unified invariant for Seifert fibered spaces and for Dehn surgeries on twist knots. We show that this invariant separates integral homology Seifert fibered spaces and can be used to detect the unknot.", "revisions": [ { "version": "v2", "updated": "2007-04-27T07:19:57.000Z" } ], "analyses": { "subjects": [ "57N10", "57M25" ], "keywords": [ "rational surgery formula", "homology seifert fibered spaces", "invariant separates integral homology seifert", "integrality" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......8627B" } } }
