The Interaction of Curvature and Topology

Snapshots of modern mathematics from Oberwolfach

The Interaction of Curvature and Topology

In this snapshot we will outline the mathematical notion of curvature by means of comparison geometry. We will then try to address questions as the ways in which curvature might influence the topology of a space, and vice versa.
