Two discrete, geometrically finite subgroups of the isometrics of hyperbolic n-space (n > 4) are defined whose intersection is infinitely generated. This settles, in dimensions 4 and above, a long-standing question in Kleinian and hyperbolic groups reiterated at a problem session chaired by Bernard Maskit at the AMS meeting 898, March 3-5, 1995, a conference in honor of Bernard Maskit's 60th birthday.

Abstract In this paper, we obtain several results on the commensurability of two Kleinian groups and their limit sets. We prove that two finitely generated subgroups G1 and G2 of an infinite

### ON KLEINIAN GROUPS WITH THE SAME SET OF AXES

• Mathematics
Bulletin of the Australian Mathematical Society
• 2008
Abstract J. W. Anderson (1996) asked whether two finitely generated Kleinian groups $G_{1}, G_{2}\subset \mathrm {Isom}(\mathbb {H}^{n})$ with the same set of axes are commensurable. We give some

We prove the convex combination theorem for hyperbolic n‐manifolds. Applications are given both in high dimensions and in three dimensions. One consequence is that given two geometrically finite

Abstract In this paper, we give an account of the notion of geometrical finiteness as applied to discrete groups acting on hyperbolic space of any dimension. We prove the equivalence of various

This paper deals with the discrete groups of rigid motions of the hyperbolic plane. It is known (12) that the finitely generated, orientation-preserving groups have the following presentations:

### Intersections of analytically and geometrically finite subgroups of Kleinian groups

We consider the intersection of pairs of subgroups of a Kleinian group of the second kind K whose limit sets intersect, where one subgroup G is analytically finite and the other J is geometrically

### The limit set intersection theorem for finitely generated Kleinian groups

The proof of the Theorem proceeds by showing that it holds in some special cases involving Kleinian groups with connected limit sets, and then extending to the general case by using a decomposition

Let G be a discrete subgroup of SL(2, C)/{• 1}. Then G operates as a discontinuous group of isometrics on hyperbolic 3-space, which we regard as the open unit ball B a in Euclidean 3-space E a. G
