Graphes, moyennabilité et bas du spectre de variétés topologiquement infinies

Samuel Tapie

From a graph $G$ with constant valency $v$ and a (non-compact) manifold $C$ with $v$ boundary components, we build a $G$ -periodic manifold $M$ . This process gives a class of topolo…

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…
