\vfill

\textsc{Abstract:}
I will describe the theory of hyperbolic flows on three manifolds, and then describe a new approach to chaotic flows using knot theory, allowing for topological analysis of singular flows. I'll use this to show that, surprisingly, the famous Lorenz flow on R\^{}3 can be related to the geodesic flow on the modular surface. When changing the parameters, we also find a new type of topological phases in the Lorenz system.
This will be an introductory talk.
