WebbThe space S 3 is the 3-dimensional analogue of the usual sphere in 2 dimensions. It is an isotropic space (all the directions play the same role). Among the eight Thurston geometries, it is the only compact one. It can be seen as the unit tangent bundle of the 2-sphere. This point of view is also knwon as the Hopf fibration.

Geometrization Conjecture - The Eight Thurston Geometries
Webb10 feb. 2024 · Thurston’s geometrization conjecture, also known simply as the geometrization conjecture, states that compact 3-manifolds can be decomposed into pieces with geometric structures. The geometrization conjecture is an analogue for 3-manifolds of the uniformization theorem for surfaces. Webb18 feb. 2024 · The thing to keep in mind is that (outside of a tiny number of exceptions that you probably know) the Thurston geometries occur only when the manifold is irreducible, and in that case only when the manifold is either atoroidal or is toroidal and has one of the geometries other than H 3 that allow many many toruses, namely product geometries, … scooby subs ocala fl menu

Webbdimensional Thurston geometries has grown considerably. One reason is that these spaces can be endowed with a complete metric with a large isometry group; another, more recent, is the announced proof of Thurston geometric conjecture, which ensures the dominant role of this spaces among the three-dimensional geometries.
