Twisted Patterson-Sullivan measures and applications to amenability and coverings

Rémi Coulon, Rhiannon Dougall, Barbara Schapira +1

Let $Γ^{'} < Γ$ be two discrete groups acting properly by isometries on a Gromov-hyperbolic space $X$ . We prove that their critical exponents coincide if and only if $Γ^{'}$ is co-amenable…

$A_\infty$ weights and compactness of conformal metrics under $L^{n /2}$ curvature bounds

Clara L. Aldana, Gilles Carron, Samuel Tapie

We study sequences of conformal deformations of a smooth closed Riemannian manifold of dimension $n$ , assuming uniform volume bounds and $L^{n /2}$ bounds on their scalar curvatures…

Regularity of entropy, geodesic currents and entropy at infinity

Barbara Schapira, Samuel Tapie

In this work, we introduce the notion of entropy at infinity, and define a wide class of noncompact manifolds with negative curvature, those which admit a critical gap between entr…

Discrete geometry and isotropic surfaces

François Jauberteau, Yann Rollin, Samuel Tapie

We consider smooth isotropic immersions from the 2-dimensional torus into $R^{2 n}$ , for $n \geq 2$ . When $n = 2$ the image of such map is an immersed Lagrangian torus of $R^{4}$ . We…
