This implies, together with already well-known regularity results, that finite-energy, critical $C^1$-curves $\\gamma: \\mathbb{R}/\\mathbb{Z} \\to \\mathbb{R}^n$ of generalized integral Menger curvature $\\mathrm{intM}^{(p,2)}$ subject to a fixed length constraint are not only $C^\\infty$ but also analytic. Our approach is inspired by analyticity results on critical points for O'Hara's knot energies based on Cauchy's method of majorants and a decomposition of the first variation. The main new idea is an additional iteration in the recursive estimate of the derivatives to obtain a sufficient difference in the order of regularity.", "revisions": [ { "version": "v1", "updated": "2021-03-12T16:24:42.000Z" } ], "analyses": { "subjects": [ "35A20", "35A10", "35B65", "57K10" ], "keywords": [ "critical points", "hilbert case", "analyticity", "fixed length constraint", "generalized integral menger curvature energies" ], "note": { "typesetting": "TeX", "pages": 31, "language": "en", "license": "arXiv", "status": "editable" } } }
