| Dec 31, 2023 at 18:58 | comment | added | Danny Ruberman | I don't really get the question. As you've described it, M is the projectivization of the complex line bundle of Chern class 1 over $S^2$, and hence is exactly the non-trivial $S^2$ bundle over $S^2$. Are you asking why that's a connected sum of $\pm \mathbb{C}P^2$? | |
