WebAbstract Interval exchange maps are related to geodesic flows on translation surfaces; they correspond to the first return maps of the vertical flow on a transverse segment. The Rauzy–Veech induction on the space of interval exchange maps provides a powerful tool to analyze the Teichmüller geodesic flow on the moduli space of Abelian differentials. …

WebJan 28, 2014 · Abstract. We prove some ergodic theorems for flat surfaces of finite area. The first result concerns such surfaces whose Teichmüller orbits are recurrent to a compact set of {SL (2,\mathbb {R})/SL (S,\alpha)} , where SL ( S ,α) is the Veech group of the surface.
