WebThe second part is that if I accept the fact that A ≈ S^1, then π_1(S^1 × D^2) = π_1(A) = Z and so if we have a retraction the map induced by the inlcusion A → X, ι_*: *π_*1(A) → *π_*1(S^1 × D^2) is an injection by Hatcher's proposition 1.171.17. Now it's stated that WebMath 215C Solution Set 2 3.2.1. Since M g is connected, we know that H0(M g) ∼= Z and that the generator 1 of this group is the identity in the cup product structure. Also, we know that H 2(M g) ∼= Z, so H2(M g) ∼= Z by the universal coefficients theorem for cohomology. Since Hn(M g) = 0 for n > 2, we know that θ ∈ H2(M g), θ ^ 1 = θ, while its cup product …
