Web18 mei 2024 · The Hopf fibration is a map S3 → S2. The author, however, defines it as the map p: S3 → CP1, p(z1, z2) = [z1: z2]. This is a very elegant definition, but to obtain the desired map S3 → S2 we have to identify CP1 with S2. This is done in Proposition 2.2 where CP1 is identified with the one-point-compactification ˆC = C ∪ {∞} of C.
