 Gutkin E. Geometry, topology and dynamics of geodesic flows on noncompact polygonal surfaces 2010, vol. 15, no. 4-5, pp.  482-503 Abstract We establish the background for the study of geodesics on noncompact polygonal surfaces. For illustration, we study the recurrence of geodesics on $\mathbb{Z}$-periodic polygonal surfaces. We prove, in particular, that almost all geodesics on a topologically typical $\mathbb{Z}$-periodic surface with a boundary are recurrent. Keywords: (periodic) polygonal surface, geodesic, skew product, cross-section, displacement function, recurrence, transience, ergodicity Citation: Gutkin E.,  Geometry, topology and dynamics of geodesic flows on noncompact polygonal surfaces, Regular and Chaotic Dynamics, 2010, vol. 15, no. 4-5, pp. 482-503 DOI:10.1134/S1560354710040064
