| Oct 5, 2011 at 10:20 | comment | added | uuuuuuuuuuuu | @knob call this subgroup $G$ then $B$ is the stack with the same objects of $A$ but with $Hom_B(x,y):=Hom_A(x,y)/y^{*} G$ where the action is the composition action @Keerthi Madapusi Pera I only have these hypoteses and $A$ is not proper | |
