Poincaré Hyperbolic Disk
A 2-D space having Hyperbolic Geometry defined as the 2-Ball 
, with HyperbolicMetric
The Poincaré disk is a model for Hyperbolic Geometry, and there is an isomorphism between the Poincaré disk model and the Klein-Beltrami Model.See also Elliptic Plane, Hyperbolic Geometry, Hyperbolic Metric, Klein-Beltrami Model
