WebThe theory applies to a field extension with three properties—that it is finite-dimensional, separable, and normal. Such an extension is called a “finite Galois extension.”. The Fundamental Theorem of Galois Theory says in this case that the intermediate extensions are in one-one correspondence with subgroups of the Galois group, and it ...
