Finiteness of pseudo-Anosov flows with no perfect fits 2

Abstract/Media

Zoom Link

The finiteness conjecture for pseudo-Anosov flows predicts that every closed 3-manifold admits at most finitely many pseudo-Anosov flows up to conjugation and reparametrization. In this talk, we will explain some motivations for this conjecture, review the known results, and describe some ideas towards a proof for finiteness of pseudo-Anosov flows with no perfect fits. This is joint work with Thomas Barthelmé.
