[Abstract] [BibTeX] [DOI] [URL] [PDF] Abstract: Motivated by the Coulomb potential of an equidistributed charge on a curve, Jun O'Hara introduced and investigated the first geometric knot energy, the MÃ¶bius energy. We prove that every critical curve of this MÃ¶bius energy is of class and thus extend the corresponding result due to Freedman, He, and Wang for minimizers of the MÃ¶bius energy.

 Blatt S and Reiter P (2014), "How nice are critical knots? Regularity theory for knot energies", Journal of Physics: Conference Series. Vol. 544(1), pp. 012020. [Abstract] [BibTeX] [URL] Abstract: In this note we report on some recent developments in geometric knot theory which aims at finding links between geometric properties of a given knotted curve and its knot type. The central object of this field are so-called knot energies which are defined on closed embedded curves. First we present three important examples of two-parameter knot energy families, namely O'Hara's energies, the (generalized) integral Menger curvature, and the (generalized) tangent- point energies. Subsequently we outline the main steps that lead to C inf -regularity of stationary points- especially minimizers-in the non-degenerate sub-critical range of parameters. Particular attention is devoted to the appearing parallels between these energies which, surprisingly at first glance, are quite similar from an analyst's perspective.
