  • Critical Exponent and Hausdorff Dimension in Pseudo-Riemannian Hyperbolic Geometry IMRN (Avec Daniel Monclair)
    The aim of this article is to understand the geometry of limit sets in pseudo-Riemannian hyperbolic geometry. We focus on a class of subgroups of PO(p,q+1) introduced by Danciger, Guéritaud and Kassel, called ℍp,q-convex cocompact. We define a pseudo-Riemannian analogue of critical exponent and Hausdorff dimension of the limit set. We show that they are equal and bounded from above by the usual Hausdorff dimension of the limit set. We also prove a rigidity result in ℍ2,1=ADS3 which can be understood as a Lorentzian version of a famous Theorem of R. Bowen in 3-dimensional hyperbolic geometry.

  • Entropy of embedded surfaces in quasi-fuchsian manifolds Pacific J. of Math. We compare critical exponent for quasi-Fuchsian groups acting on the hyperbolic 3-space, ℍ3, and on invariant disks embedded in ℍ3. We give a rigidity theorem for all embedded surfaces when the action is Fuchsian and a rigidity theorem for negatively curved surfaces when the action is quasi-Fuchsian.
  • Counting closed geodesics in globally hyperbolic maximal compact AdS 3-manifolds, Geometria Dedicata We propose a definition for the length of closed geodesics in a globally hyperbolic maximal compact (GHMC) Anti-De Sitter manifold. We then prove that the number of closed geodesics of length less than R grows exponentially fast with R and the exponential growth rate is related to the critical exponent associated to the two hyperbolic surfaces coming from Mess parametrization. We get an equivalent of three results for quasi-Fuchsian manifolds in the GHMC setting: Bowen’s rigidity theorem of critical exponent, Sanders’ isolation theorem and McMullen’s examples lightening the behaviour of this exponent when the surfaces range over Teichmüller space.
