Lemma for the Fundamental Theorem of Galois Theory

A key lemma in Galois theory states that for a field extension L/K, an intermediate field M, and a K-automorphism τ of L, the set of τ-conjugates of M-automorphisms of L equals the set of M-automorphisms of τ(L). This lemma is proven by showing that the set of τ-conjugates of M-automorphisms fixes all elements of τ(M) and the set of τ-conjugates of M-automorphisms is contained in the set of ...
