Duality in the homology of 5-manifolds (2308.12390v1)
Published 23 Aug 2023 in math.AT
Abstract: 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 Poincare duality for M. However we find an obstruction to this duality.
