Here $s$ denotes the arclength and $\\kappa$ the curvature. These minimizers are automatically planar, analytic, convex curves. The straight segment, traversed back and forth, is the only possible exception that becomes admissible in a more generalized setting. In proving this, we overcome the difficulty from a lack of coercivity and compactness by a combination of methods.", "revisions": [ { "version": "v1", "updated": "2013-01-27T06:37:41.000Z" } ], "analyses": { "subjects": [ "53A04", "49J45", "49N60", "49R50" ], "keywords": [ "curvature dependent variational problem", "regularity", "principal eigenvalue", "smooth closed curves", "convex curves" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1301.6322D" } } }
