WebMath 215C - Solution Set 4 Hatcher 3.3.21 Let K beany compact set in X. We note that we can use excision to move between Hn(X+;X+ K;G) and Hn(X;X K;G) { the excision just removes the point at 1 from the open set X+ K (since by de nition, the neighborhoods of 1 in the one-point compacti cation have complements in X+ that are compact subsets of X).
