Poincare half-plane
WebSpecifically, Poincare modeled hyperbolic geometry by assigning the fundamental form. ds2 =. du2 + dv2. v2. (3) to the upper half of the uv -plane. The result is called the Poincare … The Poincaré half-plane model is named after Henri Poincaré, but it originated with Eugenio Beltrami who used it, along with the Klein model and the Poincaré disk model, to show that hyperbolic geometry was equiconsistent with Euclidean geometry . See more In non-Euclidean geometry, the Poincaré half-plane model is the upper half-plane, denoted below as H $${\displaystyle =\{\langle x,y\rangle \mid y>0;x,y\in \mathbb {R} \}}$$, together with a metric, the See more Here is how one can use compass and straightedge constructions in the model to achieve the effect of the basic constructions in the hyperbolic plane.

In particular, we can define a new geometry on the plane by giving it a non-Euclidean fundamental form.
WebBesides the unit disk, there is another equivalent representation commonly used in two-dimensional hyperbolic geometry and defining a model of hyperbolic space on the upper half-plane; namely, the Poincaré half-plane. The disk D and the upper half plane P + = {Z ∈ C, Im Z > 0} are related by a conformal map, called Möbius transformation, WebOct 11, 2013 · Henri Poincaré studied two models of hyperbolic geometry, one based on the open unit disk, the other on the upper half-plane. The half-plane model comprises the …
