| Apr 21, 2011 at 12:37 | comment | added | algori | Dear shengao -- I think there may be an example somewhere in the paper by Steenbrink and Stevens (I don't have that paper, so can't tell where exactly). | |

| Apr 20, 2011 at 15:11 | comment | added | algori | shenghao -- I think this should be false for threefolds. | |
| Apr 20, 2011 at 14:33 | comment | added | shenghao | Thanks, algori. I added the compactness assumption. In fact before posting the question, I went to look up at the same example of Serre in Hartshorne's AG, Appen. B, but didn't realize anything strange about it... | |
