Duality in the homology of 5-manifolds
Homology, Homotopy and Applications
MetadataShow full item record
We show that the homological properties of a 5-manifold M with fundamental group G are encapsulated in a G invariant stable form on the dual of the third syzygy of Z. In this notation one may express an even stronger version of Poincar e duality for M. However we find an obstruction to this duality.
