This book gives a complete proof of the geometrization conjecture, which describes all compact 3-manifolds in terms of geometric pieces, i.e. Thurston’s Geometrization Conjecture (now, a theorem of Perelman) aims to answer the question: How could you describe possible shapes of our universe?.

InGrigori Perelman sketched a proof of the geometrization conjecture by showing that the Ricci flow can indeed be continued past the singularities, and has the behavior described above. Contact the MathWorld Team.

On the other hand, the geometrisation conjecture will be rather visibly lurking beneath the surface in the discussion of this lecture. The geometry of the universal cover of the Lie group.

Also containing proofs geometrizwtion Perelman’s Theorem 7. Finite volume manifolds with this geometry are compact and orientable and have the structure of a Seifert fiber space.

Geometrization conjecture

Anna G on Elias Stein. The idea is that the Ricci flow will in general produce singularities, but one may be able to continue the Ricci flow past the singularity by using surgery to change the topology of the manifold.

Anonymous on Jean Bourgain. There is a preprint at https: See the about page for details and for other commenting policy.

It fibers over H 2. The third is the only example of a non-trivial connected sum with a geometric structure. In three dimensions, it is not always possible to assign a single geometry to a whole topological space. In mathematics, Thurston’s geometrization conjecture states that certain three-dimensional topological spaces each have a unique geometric structure that can be associated with them. At the risk of belaboring the obvious, here is the statement of that conjecture: This page was last edited on 14 Julyat Print Price 3 Label: This difficult theorem connecting the topological conjecturs geometric structure of 3-manifolds led Thurston to give his influential geometrisation conjecturewhich in principle, at least conjectrue classifies the topology of an arbitrary compact 3-manifold as a combination of eight model geometries now known as Thurston model geometries.

The classification of such manifolds is given in the article on Seifert fiber spaces.

Print Price 2 Label: All of these important topics are of independent interest. Nevertheless, a manifold can have many different geometric structures of the same type; for example, a surface of genus at least 2 has a continuum of different hyperbolic metrics.

Finite volume conjectjre with this geometry have the structure of a Seifert fiber space if they are orientable.

Before stating Thurston’s geometrization conjecture in detail, some background information is useful. There are enormous numbers of examples of these, and their classification is not completely understood. In the course of proving the geometrization conjecture, the authors provide an overview of the main results about Ricci flows with surgery on geometrizatioh manifolds, introducing the reader to this difficult material.

The point stabilizer is O 2, R. To find out more, including how to control cookies, see here: This geometry can be modeled as a left invariant geometrizafion on the Bianchi group of type II. Explore thousands of conecture applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more. The second decomposition is the Jaco-Shalen-Johannson torus decompositionwhich states that irreducible orientable compact 3- manifolds have a canonical up to isotopy minimal collection of disjointly embedded incompressible tori such that each component of the 3- manifold removed by the tori is either “atoroidal” or “Seifert-fibered.

The book also includes an fonjecture introduction to Gromov-Hausdorff limits and to the basics of the theory of Alexandrov spaces.

Most Thurston geometries can be realized as a left invariant metric on a Bianchi group. Anonymous on Polymath15, eleventh thread: This is the only model geometry that cannot be realized as a left invariant metric on a 3-dimensional Lie group.
