Abelian differential; moduli space; Teichm??ller volume
As introduced by the author, concerning the problem of studying the growth rate of the number of closed trajectories of a rational billiard, or the similar problem of studying the number of geodesic saddle loops or geodesic saddle connections on a translation surface, one needs to determine some constants which can be expressed in terms of the volumes of the corresponding strata in the moduli space of Abel differentials [\textit{A. Eskin} and \textit{H. Masur}, Ergodic Theory Dyn. Syst. 21, 443--478 (2001; Zbl 1096.37501)]. Similarly, one needs to know the volumes of the corresponding strata in the moduli space of Abel differentials when studying the topological dynamics of a generic orientable measured foliation on a Riemann surface [\textit{A. Zorich}, Am. Math. Soc. 197(46), 135--178 (1999; Zbl 0976.37012)].
In the paper under review, the author presents an approach for the calculation of these volumes by means of counting the ``integer points'' in the corresponding moduli space, in particular, he illustrates his approach by treating two examples.
