Finiteness of veering triangulations
Thomas Barthelmé, Thomas Barthelmé, Chi Cheuk Tsang +1
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…

On the set of normalized dilatations of fully-punctured pseudo-Anosov maps
Chi Cheuk Tsang
We improve the bound on the number of tetrahedra in the veering triangulation of a fully-punctured pseudo-Anosov mapping torus in terms of the normalized dilatation. When the mappi…

Endperiodic maps, splitting sequences, and branched surfaces
Michael P. Landry, Chi Cheuk Tsang
We strengthen the unpublished theorem of Gabai and Mosher that every depth one sutured manifold contains a very full dynamic branched surface by showing that the branched surface c…
