1. Energy functionals of knots II

Author

Jun O'Hara

Subjects
Knot complement, Energy, Knot, Mathematical analysis, Fibered knot, Möbius energy, Torus, Knot energy, Mathematics::Geometric Topology, Combinatorics, Knot (unit), Knot invariant, Geometry and Topology, Minimizer, Computer Science::Databases, Mathematics, Energy functional
Abstract

We study an energy functional of knots, e p j ( jp > 2), that is finite valued for embedded circles and takes +∞ for circles with double points. We show that for any b ϵ R there are finitely many solid tori T 1 ,…, T m such that any knot with e p j ⩽ b can be contained in some T i in a good manner. Then we can show the existence of a minimizer of e p j in each knot type.

Abstract

We define energy functionals on the space of embeddings from S1 into R 3 and show the finiteness of knot types under bounded values of those functionals.
