  - "Given a geometrically finite hyperbolic surface of infinite volume it is a\r\nclassical
    result of Patterson that the positive Laplace-Beltrami operator has\r\nno $L^2$-eigenvalues
    $\\geq 1/4$. In this article we prove a generalization of\r\nthis result for the
    joint $L^2$-eigenvalues of the algebra of commuting\r\ndifferential operators
    on Riemannian locally symmetric spaces $\\Gamma\\backslash\r\nG/K$ of higher rank.
    We derive dynamical assumptions on the $\\Gamma$-action on\r\nthe geodesic and
    the Satake compactifications which imply the absence of the\r\ncorresponding principal
    eigenvalues. A large class of examples fulfilling these\r\nassumptions are the
    non-compact quotients by Anosov subgroups.@eng"
