Phase transitions for the geodesic flow of a rank one surface with nonpositive curvature

Keith Burns, Jérôme Buzzi, Todd Fisher +1

We study the one parameter family of potential functions associated with the geometric potential for the geodesic flow of a compact rank 1 surface of nonpositive curva…

Accessibility and centralizers for partially hyperbolic flows

Todd Fisher, Boris Hasselblatt

Stable accessibility for partially hyperbolic diffeomorphisms is central to their ergodic theory, and we establish its \(C^1\)-density among 1. all, 2. volume-preserving, 3. symple…

Equilibrium states for natural extensions of non-uniformly expanding local homeomorphisms

Todd Fisher, Krerley Oliveira

We examine uniqueness of equilibrium states for the natural extension of a topologically exact, non-uniformly expanding, local homeomorphism with a Hölder continuous potential func…

Equilibrium states for certain partially hyperbolic attractors

Todd Fisher, Krerley Oliveira

We prove that a class of partially hyperbolic attractors introduced by Castro and Nascimento have unique equilibrium states for natural classes of potentials. We also show if the a…

A dichotomy for measures of maximal entropy near time-one maps of transitive Anosov flows

Jérôme Buzzi, Todd Fisher, Ali Tahzibi

We show that time-one maps of transitive Anosov flows of compact manifolds are accumulated by diffeomorphisms robustly satisfying the following dichotomy: either all of the measure…

Centralizers of hyperbolic and kinematic-expansive flows

Lennard Bakker, Todd Fisher, Boris Hasselblatt

We show generic hyperbolic flows (Axiom A and no cycles, but not transitive Anosov) commute with no -diffeomorphism other than a time-t map of the flow itself.…
