| Feb 4, 2022 at 16:39 | comment | added | AG learner | Thanks for showing the details of computations! This is very helpful. So, is it in general true that the normal bundle $N_{\Gamma(f)|(X\times Y)}$ of the graph $\Gamma(f)$ of a morphism $f:X\to Y$ is isomorphic to the pullback tangent bundle $f^*T_Y$ (after identifying $X$ with the graph $\Gamma(f)$)? | |
| Feb 4, 2022 at 4:49 | comment | added | Sasha | In other words, how to find its normal bundle, right? I added a computation to the answer. | |
