WebHatcher Exercise 2.1.8 We compute the simplicial homology of the complex described in the text. Fix notation to refer to the vertices of each tetrahedron in the complex: will refer to the 'th vertex on the 'th tetrahedron -- throughout this problem, used as an index ranging from to will be understood to be taken mod .

WebA map f: Sn → Sn satisfying f(x) = f( − x) for all x is called an even map. Show that an even map Sn → Sn must have even degree, and that the degree must in fact be zero when n is even. When n is odd, show there exist even maps of any given even degree. IHints: If f is even, it factors as a composition Sn → RPn → Sn.

There is a quotient map q: W → S1 to the one-point compactification S1 of R obtained by collapsing [−1,1] to a point. This map is manifestly continuous (but there is also a general reason [2]). godzilla king of the monsters trailer one

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).
