Minimum volume cusped hyperbolic three-manifolds

Understand

This paper is the second in a series whose goal is to understand the structure of low-volume complete orientable hyperbolic 3-manifolds.

• Using Mom technology, we prove that any one-cusped hyperbolic 3-manifold with volume <= 2.848 can be obtained by a Dehn filling on one of 21 cusped hyperbolic 3-manifolds.
• We also show how this result can be used to construct a complete list of all one-cusped hyperbolic three-manifolds with volume <= 2.848 and all closed hyperbolic three-manifolds with volume <= 0.943.
• In particular, the Weeks manifold is the unique smallest volume closed orientable hyperbolic 3-manifold.
