In this paper we consider billiards in a square with a barrier. We use Ratner's theorem to compute the asymptotics for the number of closed orbits. 1. Introduction Let P = P(p/q, α) denote the polygon whose boundary is the union of the boundary of the unit square ∂([0, 1] × [0, 1]) and the interval { p/q} × [0, α] (see Figure 1). We consider billiard paths;(More)

We give a self contained proof that for Kähler surfaces with non negative Kodaira dimension, the canonical class of the minimal model and the (−1)-curves, are oriented diffeomorphism invariants up to sign. This includes the case pg = 0. It implies that the Kodaira dimension is determined by the underlying differentiable manifold. We compute the Seiberg(More)
We study modular fibers of elliptic differentials, i.e. investigate spaces of coverings (Y, τ) → (C/Z ⊕ Zi, dz). For genus 2 torus covers with fixed degree we show, that the modular fibers F d (1, 1) are connected torus covers with Veech group SL 2 (Z). Using results of Eskin, Masur and Schmoll [EMS] we calculate χ(F d (1, 1)) and the parity of the spin(More)
Asymptotic quadratic growth rates of saddle connections and families of periodic cylinders on translation tori with n marked points are studied. For any marking the existence of limits of the quadratic growth rate is shown using elementary methods (not Ratners theorem). We study the growth rate limit as function of the marking. Precise formulas for this(More)
Age related atrophy of the laryngeal muscles -mainly the thyroarytenoid muscle (TAM)- leads to a glottal gap and consequently to a hoarse and dysphonic voice that significantly affects quality of life. The aim of our study was to reverse this atrophy by inducing muscular hypertrophy by unilateral functional electrical stimulation (FES) of the recurrent(More)
