A proof of stable ergodicity without accessibility

Lundi 15 octobre 10:15-11:45 - Davi Obata - Orsay

Résumé : In the last two decades several works have been done on stable ergodicity
of volume-preserving diffeomorphisms. In the partially hyperbolic world,
all the works on stable ergodicity use a notion called accessibility. In
this talk, I will present the main points in the proof of the stable
ergodicity of an example of a volume-preserving, partially hyperbolic
diffeomorphism introduced by Pierre Berger and Pablo Carrasco. The main
novelty of this proof is that it does not use accessibility.
