The paper corrects a proof and extends a theorem about linking pairings in 4-manifolds.
problem Linking pairings in 4-manifolds and their properties.
method Analyzes the embedding of multiple copies of a 4-manifold in a compact 4-manifold and examines the resulting linking pairings.
result The linking pairing on the boundary of a 4-manifold is split metabolic, generalizing Hantzsche's theorem.
