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.
