| Apr 16, 2013 at 15:28 | comment | added | IMeasy | generically - I agree - is a Z_2 - gerbe, but there are elliptic curves with bigger automorphism group, no? and I want to consider all smooth elliptic curves | |
| Apr 16, 2013 at 14:28 | comment | added | Jason Starr | Neither the Siegel upper half space nor the open subset of $\mathbb{P}(2,3)$ that you mention is the stack of elliptic curves. The stack of elliptic curves is, generically, a $\mathbb{Z}_2$-gerbe. | |
