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.…

Curvature-Free Margulis Lemma for Gromov-Hyperbolic Spaces
Gérard Besson, Gilles Courtois, Sylvestre Gallot +1
We prove curvature-free versions of the celebrated Margulis Lemma. We are interested by both the algebraic aspects and the geometric ones, with however an emphasis on the second an…

Maximizing torsional rigidity on Riemannian manifolds
Sylvestre Gallot, Andrea Loi, Lucio Cadeddu
Let be a -dimensional Riemannian manifold and be any compact connected domain in . We study the problem of finding the {\em maxima} of the functional $\…
