Algebra Book Recommendations?

In summary, "In summary, Contemporary Abstract Algebra by Joseph A. Gallian and Abstract Algebra by Michael Artin are highly recommended for beginners in abstract algebra. Both books offer clear explanations, numerous examples, and challenging problems. Gallian's book has received high praise from readers on Amazon while Artin's book is written by a world-renowned mathematician and covers a wide range of topics including linear algebra, group theory, field theory, and Galois theory. Other recommended books include Algebra by Thomas Hungerford, which is more suitable for graduate students, and Topics in Algebra by I. N. Herstein, which is a challenging book for honors students."

Could someone please suggest a good book for beginning abstract algebra (which would allow me to begin learning number theory)? I've just finished a class in Multivariable Calc. and beginning ordinary differential equations. I will be taking Linear Algebra in the fall. I've heard the name Artin (comments on his book?) So any recommendations? Thanks.

Contemporary Abstract Algebra by Joseph A. Gallian is one of the best introductory books on AA on the market. Go to amazon.com and read the reviews of how much people like the book. I used it, and it is one of the best texts overall I have ever used.

I can second Gallian, at least it's what I first learned from.

I wanted to point out that you don't need Abstract Algebra to start learning Number Theory and since Number Theory is so much funner, you can start right away. I took my first elementary number theory course (taught from Underwood Dudley's book) at the same time as an algebra course taught from Gallian. As the courses progressed we saw much overlapping of concepts, we'd hit a general theory about groups in algebra where we had seen a specific (and interesting!) special case a few days beforein number theory, and vice versa. Learning both at the same time did a great job of tying the material together. So if your goal is number theory, don't let an ignorance of algebra hold you back.

My school uses the one by Gilbert & Gilbert for the intro course. Then I had Abstract Algebra by I Herstein, then for the Galois theory course I had Topics in Algebra, also by I Herstein. In Sept I'll be doing a course on modules & noncommutative rings & the book for that is Abstract Algebra by T Hungerford.

btw I borrowed that Hungerford book from our library & it hardly has any proofs in it! There was one that literally said "the proof is in 2 parts. the 1st part is easy. the 2nd part is left to the reader." lmao good thing I've got a good prof...

Yeah Artin! Thats the book! Best book on AA I've seen. He uses matrices to demonstrate the AA. And we all know how useful and applicable matrices are. Not much on number theory though. But, there are Lots of proofs, Lots of problems, and lots of clear explanations. I do not know much about any other books, but I can, and do strongly recommend this one. it should complement your linear algebra nicely. this is from a more applied perspective though, so take it as u will. What is mathematics without apllication anyway? seems like masturbation to me :biggrin:
Although, mathematics usually preceeds application, so I guess I am glad people like to masturbate :biggrin: Thanks God!

I recommend Artin, if you are a strong student, interested in learning the material from a real master.

This book was written by Michael Artin, world famous algebraic geometer, and full professor at MIT, to teach a class of MIT sophomores, when he could not find a book he thought suitable. He taught from it for several years while polishing the notes.

It has also been used at many other schools at various levels, probably usually as a junior/senior level math major course, but it could well serve some beginning graduate students.

His point of view is that linear algebra is the most important subject in mathematics, which is surely true, so he teaches group theory based on (infinite) groups of matrices instead of (finite) permutation groups.

He ties them in closely with geometry, and number theory as well to a small degree.

Although there is little on number theory, what is there is not found in any other text I know of, i.e. Minkowski's finiteness of the class group of a quadratic number field, and ideal factorization in similar concrete cases.

The big advantage of this book is the global mastery of the author of many subjects touching algebra. The material literally rolls off his fingertips, and he has taken the trouble to make it understandable, with solid effort, by a student.

Artin is virtually the only elementary book to discuss lie groups, especially the basic examples of SU(2) and SO(3). He provides the necessary topology along the way.

When he discusses field theory he also mentions transcendental field extensions and gives a lovely short proof of the Hilbert nullstellensatz, also not at all standard in algebra texts.

He is not impressed with the importance of Galois theory so leaves it to the last chapter, where he nonetheless does a beautiful job on it.

The book I am familiar with by Hungerford, Algebra, was written as a graduate text, not an undergraduate text, so that could explain the steeper learning curve one reviewer noted. As graduate books go however, Hungerford's book has an extremely full set of proofs of almost all (apparently not quite all) theorems, and lots of problems. Indeed his motivation in writing the book was to provide a book the average grad student could learn from and could read, including the proofs.

It is intended specifically to provide background preparation for the PhD algebra exam at a typical grad school.

My objection to Hungerford is that I feel he gives very little insight as to why the theorems are true, he just plods through a proof. I.e. he does not teach me as much as Artin does. My students however have said it serves a useful alternate to more motivated treatments. He has lots of examples.

There may also be a lower level version of his book I am not familiar with.

Herstein, Topics in Algebra, was written as an honors sophomore algebra book for Columbia students, so it has lots of fun challenging exercises for bright young students. The exposition to me and many of my friends, is of the sort that looks easy but goes in one ear and out the other. Opposite to Artin it focuses on finite groups, but matrices are also treated.

One problem is that algebraists multiply their matrices in the opposite direction from the rest of the universe, so if you, learn it herstein's way you can only communicate with other algebraists at first, until you learn to turn it around.

I do not recommend it unless you just happen to like it. I am not familiar with the watered down version.

I think Artin might be a little hard for many students, but once you get ready for it, maybe by reading an easier number theory book like Dudley, it is the best book available for those who are ready for the level roughly between upper level undergrad and beginning grad study.

A nice book I think is well written and easier than Artin, is Abstract Algebra: a geometric approach, by Theodore Shifrin.

Neither Shifrin nor Artin touch on multilinear algebra, except for a little on quadratic forms and the spectral theorem, i.e. there are no tensor products, or alternating products. Hungerford covers those in detail, for grad students.
