Robust transitivity versus trapping regions for partially hyperbolic diffeomorphisms

Sylvain Crovisier, Rafael Potrie

We show that among partially hyperbolic diffeomorphisms with one dimensional center there is a -open and dense subset for which either there is a proper quasi-attractor or bot…

Exotic codimension one Anosov flows

Sergio Fenley, Kathryn Mann, Rafael Potrie

We construct Anosov flows in certain circle bundles over closed hyperbolic 3-manifolds, producing counterexamples to a conjecture of Verjovsky. Some of these 4-manifolds admit infi…

Invariant sets for homeomorphisms of hyperbolic 3-manifolds

Elena Gomes, Santiago Martinchich, Rafael Potrie

We prove that under some assumptions on how points escape to infinity in the universal cover, homeomorphisms of hyperbolic 3-manifolds are forced to have several invariant sets (in…

Propagation of regularity along unstable manifolds

Thibault Lefeuvre, Rafael Potrie

Let be a flow on a smooth closed connected manifold that preserves and expands a foliation . We establish a theorem of propagation of regularity along the l…

Partially hyperbolic diffeormorphisms, ergodicity, and transverse foliations in dimension 3

S. R. Fenley, R. Potrie

We give a complete topological classification of (chain-)transitive partially hyperbolic diffeomorphisms in 3-manifolds in terms of Anosov flows, completing a program proposed by P…

Horizontality of partially hyperbolic foliations

Andy Hammerlindl, Rafael Potrie

We show exactly which Seifert manifolds support partially hyperbolic dynamical systems. In particular, a circle bundle over a higher-genus surface supports a partially hyperbolic s…
