Examples of non-trivial roots of unity at ideal points of hyperbolic 3-manifolds
نویسنده
چکیده
This paper gives examples of hyperbolic 3-manifolds whose SL(2,C) character varieties have ideal points for which the associated roots of unity are not ±1. This answers a question of Cooper, Culler, Gillet, Long, and Shalen as to whether roots of unity other than ±1 occur.

Non-integral Toroidal Dehn Surgeries
If we perform a non-trivial Dehn surgery on a hyperbolic knot in the 3-sphere, the result is usually a hyperbolic 3-manifold. However, there are exceptions: there are hyperbolic knots with surgeries that give lens spaces [1], small Seifert fiber spaces [2], [5], [7], [20], and toroidal manifolds, that is, manifolds containing (embedded) incompressible tori [6], [7]. In particular, Eudave-Muñoz ...
متن کاملWarped product and quasi-Einstein metrics
Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...
متن کاملResurgence of the Kontsevich-zagier Power Series
Abstract. Perturbative quantum field theory associates formal power series invariants to knotted objects, that is to knots or homology 3-spheres. These formal power series are known to be Gevrey, and are expected to be factorially divergent, and somehow linked to quantum invariants of knotted objects at complex roots of unity. The latter are the well-known Witten-Reshetikhin-Turaev invariants o...
متن کاملk-NORMAL SURFACES
Following Matveev, a k-normal surface in a triangulated 3-manifold is a generalization of both normal and (octagonal) almost normal surfaces. Using spines, complexity, and Turaev-Viro invariants of 3-manifolds, we prove the following results: • a minimal triangulation of a closed irreducible or a bounded hyperbolic 3-manifold contains no non-trivial k-normal sphere; • every triangulation of a c...
متن کاملThe Volume of a Hyperbolic 3-manifold with Betti Number 2
In a forthcoming paper [4] we will show that if one excludes certain special manifolds, such as fiber bundles over S, then the same estimate holds for hyperbolic manifolds with Betti number 1. Our volume estimates can be placed in context by comparing them with volume estimates for general hyperbolic manifolds, as well as with volumes of known examples. The largest known lower bound for the vol...
