Normalizers of lattices and isometry groups of arithmetic hyperbolic manifolds

Mikhail Belolipetsky, Tam Cheetham-West

We prove that every arithmetic lattice in PSL $(2, C)$ and every arithmetic lattice of the simplest type in PO $(n, 1)$ , $n \geq 2$ , is the normalizer of arbitrarily many of its…

Taut polynomials from finite quotients of fibered hyperbolic 3-manifold groups

Tam Cheetham-West, Biao Ma, Jun Ueki +1

We prove that the finite quotients of a fibered hyperbolic 3-manifold group detect the taut polynomials of fibered faces of the Thurston norm balls, whenever the monodromy map is f…

Detecting embedded surfaces using finite quotients

Tam Cheetham-West, Khanh Le

We give conditions on a Haken hyperbolic rational homology three sphere that imply that any other 3-manifold with profinitely equivalent fundamental group must also be Haken. In th…

Profinite rigidity for two-bridge links and 3-tangle Montesinos links

Tamunonye Cheetham-West, Xiaoyu Xu

For any two-bridge link or 3-tangle Montesinos link $L \subset S^{3}$ (including knot), this paper proves that $I ¨ _{1} (S^{3} - L)$ is profinitely rigid among the fundamental groups of compa…

Finite covers and strict boundary slopes of cusped hyperbolic 3-manifolds

Tamunonye Cheetham-West, Youheng Yao

We prove that if two cusped hyperbolic $3$ -manifolds admit a regular isomorphism between the profinite completions of their fundamental groups, then they share the same $A$ -polynom…

Determining knot groups by finite quotients

Tamunonye Cheetham-West, Alan W. Reid

We prove that hyperbolic 2-bridge knots are determined amongst all compact 3-manifolds by the profinite completions of their knot groups.
