    Bridging Patterson–Sullivan, Wigner, and Ruelle distributions: the graph case

    2 avril 2026 - 11:00Salle de conférences IRMA

    Consider the eigenvalue problem for the discrete Laplacian on finite regular graphs. One can relate three types of phase space distributions associated to the resulting eigenfunctions, namely Patterson–Sullivan, invariant Ruelle, and Wigner distributions. It has been shown that, on hyperbolic surfaces, these three phase-space distributions are asymptotically equivalent, naturally raising the question of whether a similar relationship holds for finite graphs. In this talk, I will show how discrete analogues of these distributions can be defined and how they relate to each other.
