|Title:||Poincare duality and aspherical manifolds|
|Seminar:||Department of Mathematics Colloquium|
|Speaker:||S. Weinberger, University of Chicago|
|The key homological feature of manifolds is Poincare duality. More than forty years ago Wall had conjectured that when this property holds in group cohomology, there is a natural geometric reason: the group is the fundamental group of a manifold whose universal cover is contractible. Although this conjecture is neither proved nor disproved, there has been some recent progress that I will hope to explain.|
