Uniform growth of groups acting on Cartan-Hadamard spaces

Gérard Besson, Gilles Courtois, Sylvain Gallot

Let $X$ be an $n$ -dimensional simply connected manifold of pinched sectional curvature $- a^{2} \leq K \leq - 1$ . There exist a positive constant $C (n, a)$ such that for any finitely ge…

Differentiable Rigidity under Ricci curvature lower bound

Laurent Bessières, Gérard Besson, Gilles Courtois +1

In this article we prove a differentiable rigidity result. Let $(Y, g)$ and $(X, g_{0})$ be two closed $n$ -dimensional Riemannian manifolds ( $n ⩾ 3$ ) and $f : Y \to X$ be a conti…

Rigidity of amalgamated product in negative curvature

Gerard Besson, Gilles Courtois, Sylvain Gallot

Let $Γ$ be the fundamental group of a compact n-dimensional riemannian manifold X of sectional curvature bounded above by -1. We suppose that $Γ$ is a free product of its subgroup…
