   Title: Finite volume, noncompact manifolds of negative curvature

    Abstract: Let M be a noncompact, complete, Riemannian manifold. Gromov
proved that if the sectional curvature of M is negative and bounded, and if
the volume of M is finite, then M is homeomorphic to the interior of a
compact manifold with boundary. In other words, M has finitely many ends,
and each end of M is topologically a product C×[0, ∞) of a closed manifold
C with a ray. I will discuss the question what topological restrictions
there are on each end of such a manifold M. This talk will be accessible to
a general audience.
