| Mar 22, 2010 at 13:54 | comment | added | Andrea Ferretti | I'm sorry I cannot choose two right answers. Your comment about 3) being a manifestation of 1) in the case of stacks was very interesting, but I think Peter's answer gives a more unified point of view. | |
| Mar 20, 2010 at 0:34 | comment | added | Andrea Ferretti | The connection between 1) and 3) was instead unexpected to me. | |
| Mar 20, 2010 at 0:32 | comment | added | Andrea Ferretti | Indeed this is what I meant in the last sentence before the question. But I don't know any way to prove 2) from 1) in general. | |
