"Webhave a two-sheeted covering map p: S 2!RP sending a pair of antipodal points on the sphere to their equivalence class in RP2. By Problem 11 of HW#2, this implies that for any x2RP2 there’s a set bijection ˇ 1(RP2) !p 1(x). Therefore ˇ 1(RP2) has two elements, and hence must be the group Z 2, the only group of order two.

WebFor i = 1,2, let Bi be an open neighbourhood of some point in Si homeomorphic to the open disk in R2. Then ∂(S i − Bi) ≃ S1 for i = 1,2. Take any homeomor-phism f : ∂(S1 − B1) → ∂(S2 − B2). Then S1 ∪f S2 is called the connect sum of S1 and S2 and is independent of the choices of the neighbourhoods and the map f. It is denoted ... WebReal projective space RP n is a compactification of Euclidean space R n. For each possible "direction" in which points in R n can "escape", one new point at infinity is added (but each direction is identified with its opposite). The Alexandroff one-point compactification of R we constructed in the example above is in fact homeomorphic to RP 1.
