## Dynamical zeta functions, trace formulae and applications

### Lundi 13 mai 2019 15:15-16:15 - Xenia Spilioti - Fachbereich Mathematik, Universität Tübingen

Résumé : The dynamical zeta functions of Ruelle and Selberg are functions of a complex variable $s$ and are associated with the geodesic flow on the unit sphere bundle of a compact hyperbolic manifold. Their representation by Euler-type products traces back to the Riemann zeta function. In this talk, we will present trace formulae and Lefschetz formulae, and the machinery that they provide to study the analytic properties of the dynamical zeta functions and their relation to spectral invariants. In addition, we will present other applications of the Lefschetz formula, such as the prime geodesic theorem for locally symmetric spaces of higher rank.
