Abstract (Original language)
Résumé

The aim of this note is to prove that the $L^{2}$ -Alexander invariant, a knot invariant defined using $L^{2}$ -torsions, detects the unknot.

Le but de cette note est de démontrer que lʼinvariant dʼAlexander $L^{2}$ , un invariant de nœuds défini via des torsions $L^{2}$ , détecte le nœud trivial.
