| Aug 12, 2013 at 8:19 | comment | added | Lennart Meier | @Zsolt: Why is your first sentence true? I know this result only for tame DM-stacks. | |
| Mar 16, 2010 at 11:02 | comment | added | Andrea Ferretti | Their speculation that some smooth stack mey be hiding behind the singularities of the minimal model program seems particularly interesting. Has this line been pursued any further? | |
