Moreover, c= f( ). In particular, is a root of fif and only if x divides f(x). WebIn this handout we use the more hands-on method of the Primitive Element Theorem (as in the lectures too). The reader is invited to decide which approach to the proofs they nd preferable. 1. Artin’s Lemma The key to the proof is the so-called Lemma of Artin, which concerns a nite subgroup Gof the automorphism group Aut(K) of an abstract eld K.
