http://www.map.mpim-bonn.mpg.de/Aspherical_manifolds Euclidean 3-space is the most important example of a 3-manifold, as all others are defined in relation to it. This is just the standard 3-dimensional vector space over the real numbers. A 3-sphere is a higher-dimensional analogue of a sphere. It consists of the set of points equidistant from a fixed central point in 4-dimensional Euclidean space. …

The Classification Problem for 3-Manifolds
WebThe geometry of TRS-manifold is important because of Thurston’s conjecture (cf. Reference ), now known as Geometrization-Conjecture, which gave eight geometries on a 3-dimensional manifold, namely Spherical geometry S 3, Euclidean geometry E 3, Hyperbolic geometry H 3, the geometry of S 2 × R, the geometry of H 2 × R, the geometry of ... Web23. mar 2024 · Spherical 3-Manifolds Bounding Rational Homology Balls D. H. Choe, Kyungbae Park Published 23 March 2024 Mathematics Michigan Mathematical Journal We give a complete classification of the spherical 3-manifolds that bound smooth rational homology 4-balls. Web19. sep 2024 · It says that closed orientable irreducible 3-manifold can be cut along set of incompressible tori onto pieces which are: atoroidal or Seifert-fibered. hyperbolic or Seifert-fibered. hyperbolic or spherical or Seifert-fibered with infinite fundamental group.
