Geometrization conjecture – Wikipedia

There can be more than one way to decompose a closed 3-manifold into pieces with geometric structures. 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. All of these important topics are of independent interest.

What’s new Updates on my research and expository papers, discussion of open problems, and other maths-related topics. The corresponding manifolds are exactly the closed 3-manifolds with finite fundamental group. Articles with inconsistent citation formats. There is a preprint at https: There is the paper of Shioya and Yamaguchi [2] that uses Perelman’s stability theorem [3] and a fibration theorem for Alexandrov spaces.

Six of these geometries are now well understood, and there has been a great deal of progress with hyperbolic geometry the geometry of constant negative scalar curvature. Publication Month and Year: In the course of proving the geometrization conjecture, the authors provide an overview of the main results about Ricci flows with surgery on 3-dimensional manifolds, introducing the reader to this difficult material.

Finite volume manifolds with this geometry are all compact and have the structure of a Seifert fiber space often in several ways.

European Mathematical Society, Zurich, W… Anonymous on Polymath15, eleventh thread: Sometimes this condition is included in the definition of a model geometry. Author s Product display: If a given manifold admits a geometric structure, then it admits one whose geometrizaation is maximal. Examples include the product of a hyperbolic surface with a circle, or more generally the mapping torus of an isometry of a hyperbolic surface.

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. Infinite volume manifolds can have many different types of geometric structure: Most Thurston geometries can be realized as a left invariant metric on a Bianchi group. For example, the mapping torus of an Anosov map of a torus has a finite volume conjecrure structure, but its JSJ decomposition cuts it open along one torus to produce a product of a torus and a unit interval, and the interior of this has no finite volume geometric structure.

This is established by showing that the Gromov-Hausdorff gometrization of sequences of more and more locally volume collapsed 3-manifolds are Alexandrov spaces of dimension at most 2 and then classifying these Alexandrov spaces. In addition, a complete picture of the local structure of Alexandrov surfaces is developed. Available at the AMS Bookstore. Ben Eastaugh and Chris Sternal-Johnson.

This is the only model geometry that cannot be realized as a left invariant metric on a 3-dimensional Lie group.
