Journal ArticleDOI
Asymptotic growth and least common multiples in groups
TL;DR: In this article, the authors relate word and normal subgroup growth to certain functions that arise in the quantification of residual finiteness, and investigate the asymptotic behavior of these functions.

Absolute profinite rigidity and hyperbolic geometry
TL;DR: In this article, the Bianchi group is shown to be rigid in the sense that the set of finite quotients of the group can be distinguished from all other finitely generated, residually finite groups.
Journal ArticleDOI
Peripheral separability and cusps of arithmetic hyperbolic orbifolds.
TL;DR: In this article, it was shown that the subgroup separability result of the (2n + 1)-dimensional Heisenberg group can be generalized to the (4n + 3)-dimensional quaternionic group n 4 n + 3 (H) for X = R, C, or H. A necessary and sufficient condition for such manifolds to be diffeomorphic to a cusp cross-section of an arithmetic X-hyperbolic (n+ 1)-orbifold is given.
Journal ArticleDOI
Length and Eigenvalue Equivalence
TL;DR: In this article, a general construction of eigenvalue equivalent and primitive length equivalent Riemannian manifolds is given, where the eigenvalues of the Laplace-Beltrami operator are equal (ignoring multiplicities).
Journal ArticleDOI
Extremal behavior of divisibility functions
TL;DR: In this paper, the authors studied the extremal behavior of divisibility functions for finitely generated groups and showed that the growth rate of such functions is polynomial for finite groups.
