1. A Poincaré duality space (abbreviated P.D. space) of dimension n ^ 0 is a finite complex M with the following property. Let M be embedded in S, k large, and let Rhea, regular neighborhood; then the inclusion dRClR, when converted to a fibration, has fiber a (k — 1)-sphere. Similarly a Poincaré cobordism (W; M0, Mi) of dimension n+1 is a triad with the following property. Let W; Mo, Mx be embedded in S X(I; {o}, {l}) with relative regular neighborhood R (i.e. Rf^SX {i} « Q% is a regular… Expand
