For every flat knot type and any Riemannian metric g we introduce a Conley index associated with the curve shortening flow on the space of immersed curves on M^2. We conclude existence of closed geodesics with prescribed flat knot types, provided the associated Conley index is nontrivial.", "revisions": [ { "version": "v1", "updated": "2007-05-21T16:30:44.000Z" } ], "analyses": { "subjects": [ "53C44", "53C22", "58E10" ], "keywords": [ "closed geodesics", "prescribed flat knot types", "riemannian metric", "curve shortening flow", "conclude existence" ], "tags": [ "journal article" ], "publication": { "publisher": "Princeton University and the Institute for Advanced Study", "journal": "Ann.
