Abstract

A positive integer mm will be called a {\it finitistic order} for an element γ\gamma of a group Γ\Gamma if there exist a finite group GG and a homomorphism h:ΓGh:\Gamma\to G such that h(γ)h(\gamma) has order mm in GG. It is shown that up to conjugacy, all but finitely many elements of a given finitely generated, torsion-free Kleinian group admit a given integer m>2m>2 as a finitistic order.

Comments

21 pp. I have largely rewritten Section 2 in order to correct the statement of Proposition 2.7. The original statement was not logically clear, and was not well adapted to an application in the more recent paper [22]
