Taut branched surfaces from veering triangulations

Michael Landry

Algebraic & Geometric Topology 18 (2018) 1089–1114
Abstract

Let M be a closed hyperbolic 3–manifold with a fibered face σ of the unit ball of the Thurston norm on H2(M). If M satisfies a certain condition related to Agol’s veering triangulations, we construct a taut branched surface in M spanning σ. This partially answers a 1986 question of Oertel, and extends an earlier partial answer due to Mosher.
