Exercises on Galois Theory

Question

I need a source for exercises on classical Galois Theory, or to be more specific, Galois extensions of finite fields and the rationals as well as applications (solvability by radicals, for example). So far, I have worked with Tignol's "Galois Theory of Algebraic Equations". Any additional suggestions would be appreciated, whether it is a textbook or a website, but the language should be English. Solutions are welcome, but no necessity.

Thanks in advance!

Answer 1

I really like the exercises in Lang's Algebra. There's a little bit of everything in there.

Milne's notes have exercises at the end of every chapter, a chapter of review exercises, and a two-hour exam; solutions (or at least hints) for all of these are given at the end. A lot of the action takes place over $\mathbf Q$, but I saw a fair number of questions about finite fields and they seemed good.

Keith Conrad's handouts don't have a lot of exercises, but when I had to review this stuff I found it helpful to look at the statements of his examples, try them for myself, and then read his methods. There are usually myriad ways to solve exercises in this area.

Teruyoshi Yoshida has fun example sheets, in addition to complete course notes.

Answer 2

Try these books:

• Classical Galois Theory with Examples
• Exploratory Galois Theory
• Galois Theory for Beginners: A Historical Perspective

Answer 3

You could try the fairly recent Galois Theory Through Exercises by Brzezinski. (See here for MAA review.)
