| Dec 12, 2012 at 11:22 | comment | added | Piotr Achinger | Then I guess this is just a descent question for $\bar\mathbb{Q}_l$-sheaves and morphisms between them, and the derived category doesn't play a role here. I think this should be true and that you should just push $K$ forward to $X/A$ and take invariants. | |

| Dec 11, 2012 at 22:22 | comment | added | Piotr Achinger | What exactly do you mean by "$K$ is equivariant with respect to $A$" if $K$ is just an object in the derived category? Is $a^* K$ required to be isomorphic, or just quasi-isomorphic to $K$? | |
