Counting problems in hyperbolic spaces
Abstract: On can associate to a group of isometries acting discretely on a metric space a function which measures the number of points in the orbit contained in some ball of radius R. This function is called the orbital function and any control of it when the radius R is getting large is called a counting theorem. Counting problems in a hyperbolic setting have been studied for more that 60 years now from both dynamical and analytic perspectives. In this talk, we will focus on the dynamical ones developed by Margulis seminal PhD work and widely improved after. We will show how powerful is the method but how crucial is the assumption so that people working this research area are mainly concern about how to drop it at the moment. We will conclude with proposing a new method relying on Brownian motion which actually drops the assumption but gives weaker results.
