Title:Applications of topology of three-dimensional manifolds to dynamics, I.
Seminar:Working Seminar: Dynamics and its Working Tools
Speaker:Raul Ures, IMERL, Montevideo
Abstract:
We will show that some tools of the theory of foliations, laminations and decompositions of 3-manifolds are very useful in the study of ergodic properties of partially hyperbolic diffeomorphisms. In this talk we plan to show what happens if a partially hyperbolic diffeomorphism does not satisfy the accessibility property. This leads to three type of obstructions that we will describe and, as a consequence, we will prove that on nilmanifolds any conservative partially hyperbolic diffeomorphism is accessible.
