Uniqueness of gluings and virtual finiteness of pseudo-Anosov flows on graph manifolds
Thomas Barthelmé, Neige Paulet
In this article, we give a characterization of when two pseudo-Anosov flows obtained via gluings of pieces of pseudo-Anosov flows are orbit equivalent. As an application of this wo…

Finiteness of veering triangulations
Thomas Barthelmé, Chi Cheuk Tsang, Jonathan Zung
We show that a finite volume cusped hyperbolic 3-manifold admits at most finitely many veering triangulations, and in fact this number is bounded above by the number of Giroux tors…

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…
