Learning outcomes
The student will learn the theory of Teichmuller spaces. The main viewpoint will be that of abelian differentials on Riemann surfaces and traslation surfaces, with links to hyperbolic surfaces. Some dynamical aspects such as geodesic and horocyclic flows will be studied in detail.
Course contents
Geometry of the hyperbolic plane in the half plane model and action of SL(2,R). Geodesic flow and horocyclic flow. Fuchsian groups and their quotients. Teichmuller space. Ergodic theory and invariant measures. Introduction to Ratner theory.
