This implies, together with the main result in \\cite{BR13}, that bounded energy critical points of $\\mathcal{E}^{\\alpha,1}$ subject to a fixed length constraint are not only $C^\\infty$ but also analytic. Our approach is based on Cauchy's method of majorants and a decomposition of the gradient that was adapted from the M\\\"obius energy case $\\mathcal{E}^{2,1}$ in \\cite{BV19}.", "revisions": [ { "version": "v1", "updated": "2019-04-30T09:58:50.000Z" } ], "analyses": { "subjects": [ "35B65", "57M25" ], "keywords": [ "oharas knot energies", "analyticity", "fixed length constraint", "smoothness", "regularity" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
