| Apr 21, 2012 at 2:56 | comment | added | Misha | @Igor: Kollar wrote an example for our paper arxiv.org/pdf/1109.4047.pdf (Example 34). The example is obtained by gluing two projective planes along three generic projective lines (with a twist). The result has no nontrivial line bundles, so it is not projective. | |
