On établit un théorème d'indice S1-équivariant pour les opérateurs de Dirac sur des Z/k variétés. On donne une application de ce résultat, qui généralise le théorème d'Atiyah–Hirzebruch sur les actions de S1 aux Z/k variétés.

We establish an S1-equivariant index theorem for Dirac operators on Z/k-manifolds. As an application, we generalize the Atiyah–Hirzebruch vanishing theorem for S1-actions on closed spin manifolds to the case of Z/k-manifolds.
