"Homotopy Classification of PD_4-Complexes"
Abstract: In this talk we define an order relation among oriented PD_4-complexes.We show that with respect to this relation, two PD_4-complexes over the same complex are homotopy equivalent if and only if there is an isometry between the second homology groups. We also consider minimal objects of this relation. This is a joint work with Friedrich Hegenbarth and Dusan Repovs.
