| 2 days ago | comment | added | User43029 | So, I took a look at Mumford's book, but this is not quite yet what I am asking. I understand things could go wrong in the quotient and that is why he developed the theory of quotients with linearized sheaves, but what I am looking for is a concrete example where the quotient does not work, besides the classical one of C^* acting on A^n, because there, the action is not free. | |
