Abstract

In [Jo14] and [Jo18] Vaughan Jones introduced a construction which yields oriented knots and links from elements of the oriented Thompson group F\vec{F}. In this paper we prove, by analogy with Alexander's classical theorem establishing that every knot or link can be represented as a closed braid, that given an oriented knot/link L\vec{L}, there exists an element gg in F\vec{F} whose closure L(g)\vec{\mathcal{L}}(g) is L\vec L.
