Abstract

Let NN be a complete hyperbolic 3-manifold with finitely generated fundamental group, and let HH be its convex core. We show that there is an upper bound on the radius of an embedded hyperbolic ball in HH , which depends only on the topology of NN . As a consequence, we deduce that limit sets of strongly convergent kleinian groups converge.
