A characterization of pseudo-Anosov orbit spaces via bifoliated planes
Kathryn Mann, Samuel J. Taylor
We characterize the actions on bifoliated planes that arise as orbits spaces of transitive pseudo-Anosov flows on orientable closed 3-manifold. We use branched covers, veering tria…

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…

Pseudo-Anosov flows and the geometry of Anosov-like group actions
Thomas Barthelmé, Kathryn Mann, Neige Paulet +1
We show that the action on its orbit space induced by a pseudo-Anosov flow on a closed -manifold (and more general Anosov-like actions) can be seen as an isometric action on a G…
