Equidistribution of cusp forms on PSL 2 (𝐙)∖ PSL 2 (𝐑)
Annales de l'Institut Fourier, Tome 47 (1997) no. 3, pp. 967-984.

Nous donnons la preuve d’une version microlocale d’un résultat de W. Luo et P. Sarnak concernant la répartition asymptotique des fonctions de Wigner associées aux formes paraboliques sur PSL 2 (Z)∖ PSL 2 (R).

We prove a microlocal version of the equidistribution theorem for Wigner distributions associated to cusp forms on PSL 2 (Z)∖ PSL 2 (R). This generalizes a recent result of W. Luo and P. Sarnak who prove equidistribution on PSL 2 (Z)∖H.
