Large deviations for random walks on Gromov-hyperbolic spaces

Adrien Boulanger, Pierre Mathieu, Cagri Sert +1

Let $Γ$ be a countable group acting on a geodesic Gromov-hyperbolic metric space $X$ and $μ$ a probability measure on $Γ$ whose support generates a non-elementary subsemigroup. Und…

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…

The Dirichlet random walk

Adrien Boulanger, Olivier Glorieux

In this article we define and study a stochastic process on Galoisian covers of compact manifolds. The successive positions of the process are defined recursively by picking a poin…
