An expansion of F̃ p

Let K be a field of characteristic p . The map τ ( X ) = X p − X is an additive endomorphism of K , with kernel F p . The Galois extensions of K of order p are obtained by adjoining to K solutions to equations of the form X p − X = a for some a in K . These extensions are called the Artin-Schreier e...
