Galois Theoryhe Galois group and their classifications. We shall mention a number of fundamental unsolved problems, the most notable of which is whether given a finite group G, there exists a Galois extension of Q having this group as Galois group. Three surveys give recent points of view on those questions and sizeable bibliographies:

Extensions of Ringsly at how the Galois automorphisms operate on prime ideals or the residue class fields. The two examples given after Theorem 2.9 show the importance of working over rings, to get families of extensions in two very different contexts.

Polynomials certain statements of algebra are universally true. To prove them, one proves them first for elements of a polynomial ring over Z, and then one obtains the statement in arbitrary fields (or commutative rings as the case may be) by specialization. The Cayley-Hamilton theorem of Chapter XV, for instance, can be proved in that way.
