Obiettivo del progetto (Objective)
'Dynamics on polygonal billiard tables is best understood by unfolding the table and studying the resulting flat surface. The moduli space of flat surfaces carries a natural action of SL(2,R) and all the questions about Lie group actions on homogeneous spaces reappear in this non-homogeneous setting in an even more interesting way. Closed SL(2,R)-orbits give rise to totally geodesic subvarieties of the moduli space of curves, called Teichmueller curves. Their classifcation is a major goal over the coming years. The applicant's algebraic characterization of Teichmueller curves plus the comprehension of the Deligne-Mumford compactification of Hilbert modular varities make this goal feasible. on polygonal billiard tables is best understood unfolding the table and studying the resulting surface.
