Apr 1 at 0:45 | comment | added | Kenta Suzuki | Is the statement about $\mathbb P^1\times\mathbb P^1$ correct? The line bundle $E=\mathcal O(0,-2) $ has cohomology in degree $1$ since $H^1(\mathcal O(m,n))=H^0(\mathcal O(m))\otimes H^1(\mathcal O(n))\oplus H^1(\mathcal O(m))\otimes H^0(\mathcal O(n))$. | |
