Webetry, the Poincar e disc model and the upper half-plane model. De nition 1.1. The disc model of hyperbolic space, D, consists of the unit disc in the complex plane, that is, the set U= fz= x+ iyj p x2 + y2 <1g. The metric of Dis ds2 = 4(dx 2+dy2) (1 x2+y2)2 = dzdz (1j zj2)2. De nition 1.2. The upper half-plane model of hyperbolic space, H ... WebHalfPlane. HalfPlane [ { p1, p2 }, w] represents the half-plane bounded by the line through p1 and p2 and extended in the direction w. HalfPlane [ p, v, w] represents the half-plane bounded by the line through p along v and extended in the direction w.

Webwith the closed unit disk in C. Any isometry f ∈ Isom(H. 2)takes geodesic rays to geodesic rays, clearly preserving equivalence classes. Also, f takes half-planes to half-planes. It . follows that f extends uniquely to a map f : H. 2 → H 2. As any pair of dis tinct points in ∂H 2 are the endpoints of a unique geodesic in H 2, it follows WebProposition 1.2.5. X is an admissible open subdomain of P1 and the coverings of X by the families fX n g1 =1 and fX g1 are admissible coverings. In the latter case, the covering is by open a noid domains. Proof. See the discussion following Lemma 3 in [35]. 1.2.2. The ring O X of entire functions on X. The ring of entire functions on O green eye up close
