Event description: 

The work of Thurston, Fried, McMullen, Mosher, Fenley and others weaves together a rich picture of fibrations and flows in 3-manifolds, linking growth rates of orbits, dilatations of pseudo-Anosov maps, and Thurston's norm on homology. I'll describe some of this picture and talk about some joint work with Michael Landry and Sam Taylor which develops a combinatorial model using the "veering triangulations" of Agol-Gueritaud, which permits some computations and refines our understanding a bit.
