Abstract: Any holomorphic quadratic differentials on a compact Riemann surface induces a flat metric with conical singularities. Each regular closed geodesic on the flat metric is contained in a maximal flat cylinder. In this talk, I will survey some of our recent research on the distribution of flat cylinders.
