We study the homeomorphism types of certain covers of (always orientable) surfaces, usually of infinite-type. We show that every surface with non-abelian fundamental group is cover…

Subgroups of bounded rank in hyperbolic 3-manifold groups
Ian Biringer
We prove a finiteness theorem for subgroups of bounded rank in hyperbolic -manifold groups. As a consequence, we show that every bounded rank covering tower of closed hyperbolic…
