This will be a gentle introduction to the theory of pseudo-Anosov flows on 3-manifolds, as seen from the perspective of a topologist and not a dynamicist.
I will start by considering geodesic flows on the unit tangent bundles of hyperbolic surfaces. This will lead to a definition of an Anosov and then a pseudo-Anosov flow on a 3-manifold. After discussing a couple of examples, I will outline some connections between pseudo-Anosov flows and other aspects of 3-manifold topology/ geometry/ group theory.
