Forgetful maps between Deligne-Mostow ball quotients

Martin Deraux

We study forgetful maps between Deligne-Mostow moduli spaces of weighted points on P^1, and classify the forgetful maps that extend to a map of orbifolds between the stable complet…

Minimal hypersurfaces in $\HH^n \times \R$, total curvature and index

Pierre Bérard, Ricardo Sa Earp

In this paper, we consider minimal hypersurfaces in the product space $H^{n} \times R$ . We begin by studying examples of rotation hypersurfaces and hypersurfaces in…

Bas du spectre de surfaces hyperboliques de volume infini

Samuel Tapie

This article presents some methods to control the bottom of the spectrum of the Laplacian $λ_{0}$ on hyperbolic surfaces with infinite volume. Our first result bounds the $λ_{0}$ of a…

On Perelman's Dilaton

Marco Caldarelli, Giovanni Catino, Zindine Djadli +2

By means of a Kaluza-Klein type argument we show that the Perelman's F-functional is the Einstein-Hilbert action in a space with extra ``phantom'' dimensions. In this way, we try t…

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…

Almost homogeneous manifolds with boundary

Benoit Kloeckner

Let $ρ_{0}$ be an action of a Lie group on a manifold with boundary that is transitive on the interior. We study the set of actions that are topologically conjugate to $ρ_{0}$ , up to s…
