GaloisTheory - University of Illinois Urbana-Champaign

faculty.math.illinois.edu

Galois theory is based on a remarkable correspondence between subgroups of the Galois group of an extension E/Fand intermediate fields between Eand F. In this section we will set up the machinery for the fundamental theorem. [A remark on notation: Throughout the chapter,the compositionτ σof two automorphisms will be written as a product τσ.]
