| Dec 3, 2010 at 2:43 | comment | added | t3suji | " It's an increasing union of quotient stacks [A/G] of projective varieties by finite-dimensional groups." Shouldn't it be "quasi-projective varieties"? (Or maybe something strange is going on here.) | |

| Oct 21, 2009 at 3:05 | comment | added | Charles Siegel | Well, I'm actually quite fine with Artin stacks and such. Here, I was more thinking about what happens when you take a specific unstable bundle, and what you can say about it, and also partly why (other than to get a GIT quotient) it might be bad. However, thanks for doing a few things explicitly that I'd been meaning to work through. | |
