NonEuclid is Java Software for Interactively Creating Straightedge and Collapsible Compass constructions in both the Poincare Disk Model of Hyperbolic Geometry for use in High School and Undergraduate Education. Hyperbolic Geometry used in Einstein's ...
Apr 30, 2020 · We describe formalization of the Poincaré disc model of hyperbolic geometry within the Isabelle/HOL proof assistant. The model is defined within the complex projective line $$\\mathbb {C}{}P^1$$ C P 1 and is shown to satisfy Tarski’s axioms except for Euclid’s axiom—it is shown to satisfy it’s negation, and, moreover, to satisfy the existence of limiting parallels axiom.

4 The Poincare Disc Model and Metric 11 5 Hyperbolic Geodesics 14 6 The Hyperbolic Pythagorean Theorem 16 The proofs and ideas in the rst four sections are accredited to Anderson [1] unless otherwise stated. The material in the fth section is accredited to Gamelin [2] and the proofs and ideas in the sixth section are due to Unger [3].
In the Poincaré disk model ( see figure, top right), the hyperbolic surface is mapped to the interior of a circular disk, with hyperbolic geodesics mapping to circular arcs (or diameters) in the disk that meet the bounding circle at right angles. In the Poincaré upper half-plane model…. Other articles where Poincaré disk model is discussed ...
5.1: The Poincaré Disk Model. The Poincaré disk model for hyperbolic geometry is the pair (D,H) where D consists of all points z in C such that |z|<1, and H consists of all Möbius transformations T for which T (D)=D. The set D is called the hyperbolic plane, and H is called the transformation group in hyperbolic geometry.
Feb 9, 2018 · Poincaré disc model. The Poincaré disc model for H2 ℍ 2 is the disc {(x,y) ∈ R2:x2+y2 < 1} { ( x, y) ∈ ℝ 2: x 2 + y 2 < 1 } in which a point is similar to the Euclidean point and a line must be one of the following: •. a diameter (excluding its endpoints) of the unit circle; •. an arc (excluding its endpoints) of a circle such ...
