Formulated in the language of graphs, the result is the construction of a bijective correspondence between the isotopy classes of links in $S^3$ and a class of vertex-labelled, finite acyclic graphs, called companionship graphs. This construction can be thought of as a uniqueness theorem for Schubert's `satellite operations.' We identify precisely which graphs are companionship graphs of knots and links respectively. We also describe how a large family of operations on knots and links affects companionship graphs. This family of operations is called `splicing' and includes, among others, the operations of: cabling, connect-sum, Whitehead doubling and the deletion of a component.", "revisions": [ { "version": "v5", "updated": "2007-10-29T07:54:00.000Z" } ], "analyses": { "subjects": [ "57M25", "57M50", "57M15" ], "keywords": [ "link complements", "jsj-decomposition", "links affects companionship graphs", "finite acyclic graphs", "uniqueness theorem" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......6523B" } } }
