We show that $V_K$ is independent of $K$ up to diffeomorphism. Thus, a single 4-manifold, along with connected sums thereof, accounts for all known examples of knots that are rationally slice but not slice.", "revisions": [ { "version": "v1", "updated": "2022-12-25T19:52:56.000Z" } ], "analyses": { "subjects": [ "57K10", "57K18" ], "keywords": [ "rationally slice knots", "rational homology ball", "strongly negative amphichiral knot", "connected sums thereof", "smoothly embedded disk" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
