And that is a very good thing because one can relatively easily make one's way through the basics of abstract algebra then hit the wall of categorical thinking and get lost and discouraged. Saal, I second the opinion, based on starting the book, that Aluffi has one of the most user-friendly intros to category theory around. Obviously this is only my personal opinion, there will certainly be others (probably knowing much more than myself on the subject) with different views on the subject. He doesn't seem to be treating group representations, but you can always find some other reference to study the subject.Īll in all, I think the book can be a really good place to learn algebra. Aluffi treats Galois theory (chapter 7, section 6).I am sure that many people will be happy to help you understand if you are working properly. You can try and post some exercises here together with your solutions. ![]() This is good because if you ever decided to look in depth at categories you would already have a baggage of examples behind you. I think that the category-theoretical approach adopted by Aluffi is really nice, and teaches you not only algebra, but basics of category theory as well. ![]() ![]()
