Felix Schlenk (Université de Neuchâtel, Switzerland) will speak in the geometry seminar on Tuesday 11 June, at 11.30am in the Salle de Profs. Felix’s title and abstract are to be announced.

Matthias’s title is *Manning’s inequality for Finsler and Reeb flows* and his abstract is below.

I will explain parts of recent work with Marcelo Alves and Alberto Abbondandolo, in which we study entropy rigidity for Reeb flows and Finsler flows. An important result in the study of the topological entropy for geodesic flows is Manning’s inequality, that bounds the topological entropy from below by the volume entropy.

I will discuss two ways to extend this result to Finsler and Reeb flows.
