| contents | In this thesis, we study the Teichmüller geodesic flow on the space of translation surfaces by introducing two related discrete-time dynamical systems. First, we discuss the Rauzy-Veech induction, highlighting its connections to interval exchange transformations and continued fraction expansions. While effective for addressing ergodic properties, this method faces challenges in counting closed orbits. Second, we introduce diagonal changes, a discretization better suited for counting and enumeration problems, initially applied to hyperelliptic components - subsets of translation surfaces with additional symmetries. Understanding closed orbits is significant due to the one-to-one correspondence with pseudo-Anosov mapping classes. After detailing this connection, we demonstrate how diagonal changes can produce a complete list of pseudo-Anosov mapping classes ordered by dilatation, and explain how to extend the algorithm to general components of strata. |
