It does not address this question directly, but obtains some nice results on the local Picard group. | |

| Jan 31, 2013 at 9:37 | comment | added | Hailong Dao | Dear Francesco, it looks fine to me. By the way, I forgot a more recent reference by Hartshorne-Polini, front.math.ucdavis.edu/1301.3222. | |
| Jan 31, 2013 at 8:58 | comment | added | Francesco Polizzi | Dear Hailong, thank you very much for your nice answer! It was the best thing I was hoping for :-) Since I started to work on these questions quite recently, and so I'm always worried of making some trivial mistake, may I ask you if the argument I sketched giving the implication (Question 2 true => Question 1 true) seems to you correct? Best, Francesco | |
