| May 25, 2015 at 17:25 | comment | added | Khedir | @LevBorisov My apologies to you as well. I indeed meant threefolds. My problem is that I don't know what to expect to be honest. All I know is that the set of automorphisms fixing an ample line bundle is finite. But I guess this leaves open the possibility of automorphisms not fixing an ample line bundle, and I simply do not know how to construct a rigid CY threefold with such automorphisms. | |

corrected definition of CY threefold

| May 25, 2015 at 17:21 | comment | added | Lev Borisov | I assume you mean CY threefolds. Why do you think they would only have a finite automorphism group? | |
| May 25, 2015 at 17:17 | comment | added | Jason Starr | Your definition is wrong. For a Calabi-Yau variety of dimension $n$, $h^n(X,\mathcal{O}_X)$ should be nonzero. | |
