On the signatures of even 4-manifolds
Published online by Cambridge University Press: 17 June 2002
Abstract
In this paper we prove a number of inequalities between the signature and the Betti numbers of a 4-manifold with even intersection form and prescribed fundamental group. Furthermore, we introduce a new geometric group invariant and discuss some of its properties.
