Let S p and S q be disjoint spheres in R n with n = p + q + 1 and let X = R n − ( S p ∪ S q). By Alexander duality, their fundamental classes yield cohomology classes in H ~ p ( X) and H ~ q ( X), respectively, say α p and α q . The cup product α p ∪ α q lies in H ~ p + q ( X) ≅ H ~ 0 ( S p ∪ S q ...
