WebIn the upper half-plane model it is very difficult to express this Euclidean distance to the hyperbolic distance between a given pair of points. One useful feature of the Poincaré disk model is that there does exist such an easily expressed relationship between the Euclidean and hyperbolic distance.

WebSep 4, 2024 · The Poincaré disk model is one way to represent hyperbolic geometry, and for most purposes it serves us very well. However, another model, called the upper half-plane model, makes some computations easier, including the calculation of the area of a triangle. Definition: Upper Half-Plane Model of Hyperbolic Geometry WebOct 1, 2024 · Let H = { ( x, y) ∈ R 2 y > 0 }, this is the hyperbolic plane (the upper half-plane model). The first fundamental form is d x 2 + d y 2 y 2. Write down the geodesic equation of the hyperbolic plane and show that geodesics in H are either straight lines with constant x or a half circle with center on the x -axis.

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 upper half plane together with a metric It is remarkable that the entire structure of the space follows from the metric, although not without some effort.

Both Poincaré models distort distances while preserving angles as measured by tangent lines. bodyshop 3000 ltd

"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 Poincaré metric, that makes it a model of two-dimensional hyperbolic geometry.
