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. In this setting, this means that the translation flow on a flat surface can be ... Webholds, and from Veech’s proof we will see that this is enough to conclude that Chowla conjecture holds. We remind that T. Tao obtained as a corollary the recent result of Gomilko-Kwietniak-Leman´czyk [8]. Let us further point out that the proof of Gomilko-Kwietniak-Leman´czyk is based essentially on Tao’s theorem on logarithmic Sarnak and ...
