2 00 5 On the ergodicity of partially hyperbolic systems Keith Burns and Amie Wilkinson


Pugh and Shub [PS3] have conjectured that essential accessibility implies ergodicity, for a C 2 , partially hyperbolic, volume-preserving diffeomorphism. We prove this conjecture under a mild center bunch-ing assumption, which is satsified by all partially hyperbolic systems with 1-dimensional center bundle. We also obtain ergodicity results for C 1… (More)
