Abstract

I will discuss the relationship between the geometry of a closed hyperbolic
3-manifold and the rank, or minimal number of generators, of its fundamental
group. Specifically, I will describe a geometric decomposition of closed
hyperbolic 3-manifolds with bounded rank and injectivity radius,
and indicate how to read off bounds for topological and geometric invariants
of the manifold, such as Heegaard genus and Cheeger constant. Joint work
with Juan Souto.
