<p dir="ltr"> 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. </p>
