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.

Thus each of the components in the decomposition is R P 2. heist to see you
