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 ... 対立関係とはWebVeech surface in the stratum H(2,2,2) of abelian differentials with 3 dou-ble zeros. Unpublished work of M.
