The visual core of a hyperbolic 3-manifold

By James W. Anderson and Richard D. Canary


In this note we introduce the notion of the visual core of a hyperbolic 3-manifold N, and explore some of its basic properties. We investigate circumstances under which the visual core V(N') of a cover N' of N embeds in N, via the usual covering map. We go on to show that if the algebraic limit of a sequence of isomorphic Kleinian groups is a generalized web group, then the visual core of the algebraic limit manifold embeds in the geometric limit manifold. Finally, we discuss the relationship between the visual core and Klein-Maskit combination along component subgroups
