. familiarity with the elementary topology of topological groups and of the real and complex number fields. Most of the material of these notes is to be found in the notes of Artin and the books of Artin,. The restriction of elements of g to L ′ are automorphisms of L ′ with L as fixed field (by definition of L). By finite galois theory these are all the elements of the galois group of L ′ /L. This...
