Jun 14, 2012 at 20:25	comment	added	Karl Schwede		Just to clarify, when you write $A \tensor_A B$, you mean $A$ is acting on itself by Frobenius. In other words, if $F : A \to A'$ is the Frobenius on $A$, you are really forming $A' \otimes_A B$, right? Otherwise, if $A$ is acting on itself by the identity, you have $a \otimes b = 1 \otimes(ab)$ which is sent to both $ab^p$ and $a^p b^p$.
