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.

WebHatcher §1.3 Ex 1.3.7 The quasi-circle W ⊂ R2 is a compactification of R with remainder W − R = [−1,1]. 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]).
