Counting closed geodesics under intersection constraints

speaker: Yann Chaubet (Université Paris-Saclay)

abstract: On a closed negatively curved surface, Margulis gave the asymptotic growth of the number of closed geodesics of bounded length, when the bound goes to infinity. In this talk, I will present a similar asymptotic result for closed geodesics for which certain intersection numbers — with a given family of pairwise disjoint simple closed geodesics — are prescribed. This result is obtained by considering the transfer operator of a dynamical scattering map related to the surface (with boundary) obtained by cutting our original surface along the simple curves.
