| Jan 12, 2010 at 23:14 | comment | added | user3208 | No it is not map of rings. No condition on A Qi | |
| Jan 12, 2010 at 23:12 | comment | added | user3208 | In my question, the characteristic is 2. Qi | |
| Jan 12, 2010 at 23:04 | comment | added | Jakob Katz | Wait, are there any additional restrictions on A? Because it seems like if there aren't, the smallest positive possibility should always be 1 for $d \geq 1$, since you can just take $A(X) = 1$ and $A(g) = 0$ for all other $g \in P$... (except in characteristic 2) edit: doh, didn't see the "let q be a power of 2". In that case I'm reasonably sure it'll always be q; it certainly can't be more. | |
| Jan 12, 2010 at 23:02 | comment | added | Charles Siegel | Surely there must be conditions on $A$ of some sort? You can't mean a map of rings, as there won't be any other than the zero map. | |
