On donne une nouvelle méthode de calcul d'intégrales orbitales utilisant le Laplacien hypoelliptique. On obtient un formalisme unifiant le théorème de l'indice d'Atiyah–Singer et la formule des traces.
We give a new approach to orbital integrals based on the hypoelliptic Laplacian. The formalism unifies the Atiyah–Singer index theorem and the trace formula.
