Thanks for the answers. By the way: > Infinite fields of characteristic p aren't perfect,
Isn't the algebraic closure of F_p perfect? For fields of characteristic p, perfect should mean that every element has a pth root. (I agree that some infinite fields of characteristic p aren't perfect, but this is not true for all of them.)
