From veering triangulations to dynamic pairs

Speaker: Henry Segerman, Oklahoma State University Date: Jan 30, 2018 Time: 3:30 PM Room: MSCS 509 Abstract: This is joint work with Saul Schleimer. Agol and Guéritaud show that if we take a closed manifold admitting a pseudo-Anosov flow without perfect fits, drilling the singular orbits of the flow give a cusped manifold that admits a veering triangulation. We prove the converse. Part of our proof goes through the theory of dynamic pairs, due to Lee Mosher. In this talk I will focus on this part of the proof. ______________________ Neil R.
