The main conjecture was first posed as a question by Al Marden [14]. Main Conjecture: If N is a hyperbolic 3-manifold with finitely generated fundamental group, then N is topologically tame, i.e. homeomorphic to the interior of a compact 3-manifold.

If a closed 3-manifold M can be covered by three open balls, then M is a connected sum of S3 and finitely many S2-bundles over S1.

Even though the field has grown tremendously, the book remains one of the best and most popular introductions to the subject.

This article gives an account of those properties which have so far received sufficient attention, especially those concerning the diffeomorphism groups of 3-manifolds. We give a summary of these properties and list some old and new results concerning them. Scalar Curvature and Geometrization Conjectures for 3 ...

A 3-manifold can be thought of as a possible shape of the universe.Just as a sphere looks like a plane to a small enough observer, all 3-manifolds look like our universe does to a small enough observer. This is made more precise in the definition below. 3-MANIFOLD GROUPS WITH THE FINITELY GENERATED … certain geometric 3-manifolds have FGIP or not. Next we give the sufficient conditions that FGIP for 3-manifold groups is preserved under torus sums or annulus sums and connect this result with a conjecture by Hempel [4].
