  • Resumen
    • We study the large eigenvalue limit for the eigenfunctions of the Laplacian, on a compact manifold of negative curvature � in fact, we only assume that the geodesic flow has the Anosov property. In the semi-classical limit, we prove that the Wigner measures associated to eigenfunctions have positive metric entropy. In particular, they cannot concentrate entirely on closed geodesics.
