Infinite Galois parallelograms
In [J. Algebra 217, 229-248 (1999; Zbl 0973.12002)] the second author and \textit{S. Monier-Derviaux} introduced the notion of a (finite) Galois parallelogram and proved the usual properties of classical Galois theory. We may consider the theory of Galois parallelograms as two-dimensional finite Galois theory. In the paper under review the authors generalize the theory of finite Galois parallelograms to infinite Galois extensions equipped with the Krull topology. The main result (Theorem 6.2) is the generalization of the main result of Galois theory to infinite Galois parallelograms.
