Postnikov, "Fundamentals of Galois theory", Noordhoff (1962) (Translated from Russian) MR0136603 Zbl 1092.12005 Comments A Galois group can be endowed with the Krull topology, making it a topological group. This topology is discrete if and only if the group is finite. For the Galois correspondence in the case of infinite Galois groups see Galois topological group . How to Cite This Entry:
