Webstudying normal extension elds and Galois theory, proving the fundamental theorem and some immediate consequences. We expand on Galois theory by exploring subnormal series of subgroups and de ne solvability with group property P, ultimately proving Galois’ Theorem. Beyond this, we study symmetric functions and large extension elds with Galois ... WebExample 3.4. All three eld extensions of Q in Example3.1are Galois over Q. De nition 3.5. When L=Kis a Galois extension, we set its Galois group Gal(L=K) to be the group of all K-automorphisms of L. When L=Kis an in nite Galois extension, it is often impossible to write down concrete formulas for elements of Gal(L=K).

Webextension L=Q which is Galois and radical, hence can be decomposed into a tower of simple radical extensions; and (ii) the Galois group of each simple radical extension is abelian. From here, one uses the Fundamental Theorem of Galois Theory to translate the problem into group theory, and then some more group theory produces the desired result.
