Nous montrons qu'une 2-forme exacte, préservée par un infranilautomorphisme hyperbolique, s'annule, et nous en déduisons deux propositions sur les flots d'Anosov géométriques et le changement du temps des suspensions.
We show that any exact 2-form, preserved by a hyperbolic infranilautomorphism, must be zero. We then deduce two propositions about geometric Anosov flows and the time change of suspensions.
