Extract

Recall that a Poincaré Duality group G is said to be smoothly realisable when there exists a smooth closed manifold XG of homotopy type K(G, 1). In this note we prove

Theorem 1. Let

be an exact sequence of groups in which each Si is a Surface group, withfor i ≠ j, Ф is finite and G is torsion free. Then the Poincaré Duality group G is smoothly realisable.
