Non euclidean space. Greenberg euclidean and non euclidean geometries freeman 1974 a2 b. Euclidean space is the fundamental space of classical geometryoriginally it was the three dimensional space of euclidean geometry but in modern mathematics there are euclidean spaces of any nonnegative integer dimension including the three dimensional space and the euclidean plane dimension two. In mathematics non euclidean geometry consists of two geometries based on axioms closely related to those specifying euclidean geometry. In both the two dimensional case and the three dimensional case the constancy of curvature ensures homogeneity of the space that is the possibility of moving figures in the.
As euclidean geometry lies at the intersection of metric geometry and affine geometry non euclidean geometry arises when either the metric requirement is relaxed or the parallel postulate is replaced with an alternative one. We also look at compacification and how we can represent. Also works on. Maths non euclidean spaces.

It was introduced by the ancient greek mathematician euclid of alexandria and the qualifier. Non euclidean geometry the shape of space tony weathers may 2 2013 duration.
As such they are primarily distinguished by their constant riemannian curvature. Rooms navigate non euclidean esque impossible spaces take in beautiful scenery duration. We look at how we can embed on type of space inside another and see that we can map between different spaces in different ways. In three dimensions there are three classes of constant curvature geometriesall are based on the first four of euclids postulates but each uses its own version of the parallel postulatethe flat geometry of everyday intuition is called euclidean geometry or parabolic geometry and the non euclidean geometries are called hyperbolic geometry or lobachevsky bolyai.
Comments references a1 m. Non euclidean spaces may also be classified from the point of view of their differential geometric properties as riemannian spaces of constant curvature this includes the case of spaces of curvature zero which are nevertheless topologically distinct from euclidean spaces. Although the term is frequently used to refer only to hyperbolic geometry common usage includes those few geometries hyperbolic and spherical that differ from but are very close to euclidean geometry see. In the latter case one obtains.
