Dear All, This week, Friday the 17th of October, Andy Hammerlindl will give a talk at USyd, Carslaw 273 at 4pm on Ergodic components of partially hyperbolic systems Abstract: In certain settings, such as on 3-dimensional manifolds, the Pugh-Shub conjectures have been established, and stable ergodicity is (open and) dense among partially hyperbolic systems. Thus, it is an interesting question as to exactly how these systems can fail to be ergodic. In this talk, Ill present my own research on the subject, giving a classification of non-ergodicity for certain families of partially hyperbolic systems. Hope to see you all there, Georg
