| Feb 17, 2014 at 17:29 | comment | added | user45766 | The more interesting question is under what kind of assumptions $\mathrm{det}\mathcal{N}_{Y/X}$ is ample ? As far as I know for $X$ a projective space this is true, but what is for example for Hirzebruch surfaces or $\mathbb{P}^1\times\mathbb{P}^1$? | |
| Feb 17, 2014 at 16:28 | comment | added | Georges Elencwajg | This is an answer to the original question which just asked for a formula for the determinant, and I gave such a formula here . The original question did not even mention the word "ample" ! | |
