A Cheeger-like inequality for coexact 1-forms

Adrien Boulanger, Gilles Courtois

We state and prove a Cheeger-like inequality for coexact 1-forms on closed orientable Riemannian manifolds.

Large deviations and rate of escape for hyperbolic random walks

Adrien Boulanger, Pierre Mathieu

Let $Γ$ be a countable group acting on a geodesic hyperbolic metric space $X$ and $μ$ a probability measure on $Γ$ which generates a non elementary semi-group. Under the necessary…

$SL_{2} (R)$ -dynamics on the moduli space of one-holed tori

Adrien Boulanger, Selim Ghazouani

We study the $SL_{2} (R)$ -action on the moduli space of (triangulable) dilation tori with one boundary component. We prove that every orbit is either closed or dense…
