Using ideas of Ozsvath-Stipsicz-Szabo as reinterpreted by Livingston, we use this structure to define a family of annular Rasmussen invariants that yield information about annular and non-annular cobordisms. Focusing on the special case of annular links obtained as braid closures, we use the behavior of the annular Rasmussen invariants to obtain a necessary condition for braid quasipositivity and a sufficient condition for right-veeringness.", "revisions": [ { "version": "v1", "updated": "2016-12-18T17:21:04.000Z" } ], "analyses": { "subjects": [ "57M27", "20F36", "81R50", "57Q60" ], "keywords": [ "annular khovanov-lee homology", "annular rasmussen invariants", "filtered chain homotopy type", "sufficient condition", "yield information" ], "note": { "typesetting": "TeX", "pages": 33, "language": "en", "license": "arXiv", "status": "editable" } } }
