Comptes Rendus. Mathématique, Tome 348 (2010) no. 21-22, pp. 1185-1189.

Le but de cette Note est de calculer explicitement l'invariant d'Alexander L2 (défini par Li et Zhang, 2006 [5,6]) dans le cas des nœuds toriques.

The aim of this Note is to present the explicit computation of the L2-Alexander invariant (defined by Li and Zhang, 2006 [5,6]) for all torus knots.
