On the horoboundary and the geometry of rays of negatively curved manifolds

Autor: Françoise, Dal'bo, Marc, Peigné, Andréa, Sambusetti

In this paper we try to compare the "horoboundary" of a (not necessarily simply connected) negatively curved complete Riemannian manifold X with the visual one and describe with explicit examples some phenomenoms wich may appear when X is not simply

Trajectoires géodésiques et horocycliques

Autor: Françoise Dal'Bo

Depuis une trentaine d'années, des liens très forts se sont tissés entre les systèmes dynamiques, l'algèbre linéaire et la théorie des nombres. Ce rapprochement entre différents domaines des mathématiques a permis de résoudre d'importantes

A classic result due to Furstenberg is the strict ergodicity of the horocycle flow for a compact hyperbolic surface. Strict ergodicity is unique ergodicity with respect to a measure of full support, and therefore implies minimality. The horocycle flo

International audience; We prove a general version of the amenability conjecture in the unified setting of a Gromov hyperbolic group G acting properly cocompactly either on its Cayley graph, or on a CAT(-1)-space. Namely, for any subgroup H of G, we

We construct convergent and divergent lattices in negative curvature and give a precise asymptotic description of the behavior of their counting function.
