| Nov 21, 2018 at 5:06 | comment | added | Shivani Sengupta | Could you please tell me the meaning of "Inside $H^2(\prod_i \mathbb C P^{n_i}, \mathbb Z)$ consider the set of nonzero integral multiples of hyperplane classes of the different factors". I don't have knowledge about it. If I take the generator of the cohomology ring $\mathbb C P^{n_i}$ is $b_i$, then in terms of generator what is the set? | |
