Homotopy types of 4-manifolds with 3-manifold fundamental groups

Jonathan A. Hillman


Abstract

We show that the homotopy type of a 4-manifold M whose fundamental group is a finitely presentable PD3-group π, and with w1(M)=w1(π) is determined by π, π2(M), k1(M) and the equivariant intersection pairing λM.

Keywords: 4-manifold, homotopy type, PD3-group, PD4-complex.
