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?.

The corresponding manifolds are exactly the closed 3-manifolds with geomterization fundamental group. Author s Product display: Thurston announced a proof in the s and since then several complete proofs have appeared in print.

## Geometrization conjecture

Thurston shared the Fields Medal for work done in proving that the conjecture held in a subset of these cases. From Wikipedia, the free donjecture. This geometry can be modeled as a left invariant metric on the Bianchi group of type IX.

Unlimited random practice problems and answers with built-in Step-by-step solutions. HOobituary Tags: Under Ricci flow manifolds with this geometry collapse to a point in finite time. Pacific Journal of Mathematics. There is a preprint at https: The group G has 2 components.

This geometry can be modeled as a left invariant metric on the Bianchi group of type III. There are enormous numbers of examples of these, and their classification is not completely understood. A model geometry is called maximal if G is maximal among groups acting smoothly and transitively on X with compact stabilizers. Thurston’s hyperbolization theorem implies that Haken manifolds satisfy the geometrization conjecture.

Hamilton to develop his Ricci flow. W… rudolph01 on Polymath15, eleventh thread: Publication Month and Year: 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.

If they are not orientable the natural fibration by circles is not necessarily a Seifert fibration: This geometry can be modeled as a left invariant metric on the Bianchi group of type II.

There are also uncountably many model geometries without compact quotients. There are now several different proofs of Perelman’s Theorem 7. Print Price 1 Label: This fibers over E 2and is the geometry of the Heisenberg group. It fibers over H 2. The book also includes an elementary introduction to Gromov-Hausdorff limits and to the basics of the theory of Alexandrov spaces. The point stabilizer is the dihedral group of order 8.

It is an analogue of the uniformization theorem for two-dimensional surfaceswhich states that every simply connected Riemann surface can be given one of three geometries Euclideansphericalor hyperbolic.

Bill Thurstonwho made fundamental contributions to our understanding of low-dimensional manifolds and related structures, died on Tuesdayaged Other examples are given by the Seifert—Weber spaceor “sufficiently complicated” Dehn surgeries on links, or most Haken manifolds. What’s new Updates on my research and expository papers, discussion of open problems, and other maths-related topics. The geometry of. All finite volume manifolds with solv geometry are compact. The case of 3-manifolds that should be spherical has been slower, but provided the spark needed for Richard S.

Writing up the results, and exploring negative t Career advice The uncertainty principle A: Articles with inconsistent citation formats. The geometry of the universal cover of the Lie group. 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.

Before stating Thurston’s geometrization conjecture in detail, some background information is useful. Collection of teaching and learning tools built by Wolfram education experts: Finite volume manifolds with this geometry are all compact, and geometrizwtion the structure of a Seifert fiber space sometimes in two ways.
