The first step, which we prove here, is to show that a knot in a lens space with a three-sphere surgery has simple (in the sense of rank) knot Floer homology. The second (conjectured) step involves showing that, for a fixed lens space, the only knots with simple Floer homology belong to a simple finite family. Using results of Baker, we provide evidence for the conjectural part of the program by showing that it holds for a certain family of knots. Coupled with work of Ni, these knots provide the first infinite family of non-trivial knots which are characterized by their knot Floer homology. As another application, we provide a Floer homology proof of a theorem of Berge.", "revisions": [ { "version": "v2", "updated": "2007-10-02T18:50:12.000Z" } ], "analyses": { "keywords": [ "knots admitting lens space surgeries", "berge conjecture", "knot floer homology", "simple floer homology belong", "first step" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0710.0357H" } } }
