On Horospherical Rigidity
Gérard Besson, Gilles Courtois, Sa'ar Hersonsky
We provide intrinsic conditions on the geometry of horospheres in a closed, negatively curved Riemannian manifold of dimension greater than or equal to 3, which guarantee that the…
Rigidity of flat holonomies
Gérard Besson, Gilles Courtois, Sa'ar Hersonsky
We prove that the existence of one horosphere in the universal cover of a closed, strictly quarter pinched, negatively curved Riemannian manifold of dimension on which th…
Scalar Curvature on some Open 3-Manifolds
Gérard Besson
This article is a survey of recent results about scalar curvature and contractible open -manifolds. It is dedicated to the memory of Professor S. S. Chern.
Finiteness Theorems for Gromov-Hyperbolic Spaces and Groups
Gérard Besson, Gilles Courtois, Sylvestre Gallot +1
In this article we prove that the set of torsion-free groups acting by isometries on a hyperbolic metric space whose entropy is bounded above and with a compact quotient is finite.…
On Scalar and Ricci Curvatures
Gerard Besson, Sylvestre Gallot
The purpose of this report is to acknowledge the influence of M. Gromov's vision of geometry on our own works. It is two-fold: in the first part we aim at describing some results,…
Open 3-manifolds which are connected sums of closed ones
Laurent Bessières, Gérard Besson, Sylvain Maillot
We consider open, oriented 3-manifolds which are infinite connected sums of closed 3-manifolds. We introduce some topological invariants for these manifolds and obtain a classifica…
