The term "hyperbolic geometry" was introduced by Felix Klein in 1871. Klein followed an initiative of Arthur Cayley to use the transformations of projective geometry to produce isometries. The idea used a conic section or quadric to define a region, and used cross ratio to define a metric.
interesting is the case of the hyperbolic plane, which we shall look at later. In fact it was the study of this, and Klein’s realization that both Euclidean and hyperbolic geometry are special cases of projective geometry, which led him to formulate his proposal. We have to realize that in the early 19th century, as for most preceding 56

This pedagogically reassuring feature was promoted by Felix Klein. It's central role in the logical foundation of geometry will be discussed later. Here we shall concentrate on discovering the features of hyperbolic geometry by working with one of its models. We defer the analytic description of this model until later.
6 days ago · Felix Klein constructed an analytic hyperbolic geometry in 1870 in which a point is represented by a pair of real numbers with. (1) (i.e., points of an open disk in the complex plane) and the distance between two points is given by. (2) The geometry generated by this formula satisfies all of Euclid's postulates except the fifth.

Dec 8, 2016 · Now that we’ve gone over the founding of hyperbolic geometry and have some sense of what it is, we’ll talk about two more influential mathematicians in the field: Felix Klein and Henri Poincare. Felix Klein Klein’s contribution to geometry is not only the famous Klein Bottle, but also his proof of the extension of the Cayley Measure on ...
