| Sep 12, 2010 at 13:23 | comment | added | t3suji | @Andre Henriques: It is surjective, so the cokernel is trivial. So it identifies the quotient of the additive group by the Frobenius kernel with the additive group. | |
| Sep 11, 2010 at 13:28 | comment | added | André Henriques | @Milne: Concerning your last sentence: Yes, it has a kernel. But what is its cokernel? | |
