WebbThe 3-dimensional geometries were described by Thurston, and Perelman proved that every 'simple' 3-manifold belongs to one of them. Thurston reasoned this way. In 3-manifolds, you can be isotropic or non-isotropic; isotropic means looking the same in every direction. If the geometry is isotropic, then it is curved the same way in every direction.

"His early work, in the early 1970s, was mainly in foliation theory. His more significant results include: • The proof that every Haefliger structure on a manifold can be integrated to a foliation (this implies, in particular, that every manifold with zero Euler characteristic admits a foliation of codimension one).

Webb27 sep. 2016 · At the beginning of this thesis we define basic notions necessary for understanding Thurston geometries: the notion of Riemannian manifold and geometric structure. After that we give a short review of all geometric structures in 2 and 3 dimensions and describe all of 8 Thurston geometries. In two of them, Sol and Nil, we … Webbarxiv.org 9 dicembre 2024. We construct rotating black holes in N=2, D=5 minimal and matter-coupled gauged supergravity, with horizons that are homogeneous but not isotropic. Such spaces belong to the eight Thurston model geometries, out of which we consider the cases Nil and SL (2,R). In the former, we use the recipe of arXiv:hep-th/0304064 to ...

Are there other three manifolds (without boundary) that admit all six of the aspherical Thurston geometries? My guess is that $ S^1 \times \mathbb{R}^2 $ admits all six, but that's just a …
