Soit r un entier >1. Une 3-variété M est dite r-périodique si et seulement si le groupe cyclique G=ℤ/rℤ agit semi-librement sur M avec un cercle comme l’ensemble des points fixes. Dans cet article, nous utilisons les invariants quantiques θ p pour établir des conditions nécessaires pour qu’une 3-variété soit périodique.
