Title: Poisson hyperplanes in hyperbolic space

Abstract: In the focus of this talk are random tessellations in hyperbolic space induced by Poisson point processes on the space of hyperbolic hyperplanes (totally geodesic subspaces of co-dimension 1). In the first part of the talk we consider the so-called k-skeleton of such tessellations and prove that, when observed in a sequence of increasing observation windows, the k-volume of the k-skeleton satisfies a central limit theorem only for dimensions 2 and 3 and that asymptotic normality fails in all higher dimensions. In the second part of the talk we determine the non-Gaussian limiting distribution for the special case k=d-1 and indicate possible generalizations.
On behalf of the organizers,
Marco Formentin
