Abstract:

I will describe some nice connections between closed

geodesics on surfaces, knot theory, continued fractions and hyperbolic

three-manifolds. Using a certain gadget called a "template" for the

modular surface, found by Ghys, it is possible to obtain an upper

bound for the volume of a geodesic (or its complement in the unit

tangent bundle) in terms of its length. This is joint work with Maxime

Bergeron and Lior Silberman.
