SABOURAU, Stéphane
Résumé
After introducing the notion of macroscopic scalar curvature, we will
present the following result. Consider a Riemannian metric on a closed
manifold admitting a hyperbolic metric. Suppose its macroscopic scalar
curvature is greater or equal to the one of the hyperbolic metric. Then
its volume is bounded away from zero.
