Algebra

Graduate Texts in Mathematics #211

by Serge Lang

This basic text for a one-year course in algebra at the graduate level thoroughly prepares students to handle the algebra they will use in all of mathematics. The author assumes that students have a basic familiarity with the language of mathematics "i.e.: sets and mapping, integers, and rational numbers." The text was thoroughly revised and enhanced in response to reviewers' comments and suggestions. Designed to improve students' retention and comprehension, the text is divided into four parts. The first introduces the basic notions of algebra. The second covers the direction of algebraic equations, including the Galois theory, and the final two parts cover the direction of linear and multilinear algebra.

Not exactly a light read. Very heavy book, good for hitting people with.

This is the kind of book which people love who already know everything that's in it (and then they pretend this is the way they would have liked to learn it).
Lang's "Algebra" is a sterilised accumulation of algebraic facts, and it makes a good algebra encyclopaedia.
To its credit, the book does cover a lot of material which one would otherwise have to look for in many different books, and I assume this is the main reason for its fame.
Unfortunately, the exposition follows the Bourbaki ideology, so it is practically useless as a textbook to learn from.

the final boss of mathematics

I'm reading this book in conjunction with an online lecture series on abstract algebra by Benedict Gross, a Harvard professor who was once the dean of Harvard undergraduate programme and then the dean of Harvard College. So I feel in safe hands, especially when this book looks as intimidating as it really is. Someone here mentioned that it was 'good for hitting people with' and I agree wholeheartedly, this is a real brick, at 900 pages, and a very unusual one at that, as bricks to my knowledge are usually of a red, earthy colour, whereas this one is yellow. I suppose this is an allusion to the fact that mathematics isn't really of this earth... (unlike what Tegmark claims...)

In any case, I'm learning abstract alg because I need to know what rings, ideals, and polynomials of multiple variables are (and how they behave) as these seem to be the main objects of study in algebraic geometry.

Excellent! Great exercises.

[Geoffrey Lee · Rating 2 out of 5]

I commend the reader who is able to get past the first chapter. While the book certainly contains a lot of information, it is presented in the most concise possible way (which sometimes can be an advantage, but often makes the proofs impossible to comprehend). The homework problems are challenging and time consuming. Most of them involve extending the (more basic) concepts presented in the text to deeper levels of abstraction. Therefore, I would recommend using this book for its exercises while having perhaps another algebra book to actually learn the subject (Hungerford's book is excellent).

I love Lang's Algebra, and fully understand that this makes me a minority, even in the algebra community. It's amazing as a reference, the exercises range from perfunctory to really hard (some of them reach far beyond the text, and include citations of research papers), and it's relatively readable, if a bit formulaic at times. To me this indicates an intent to expose the reader to both the fundamentals and some beautiful math.

The very reason that I don't like it is my lack of understanding. Of course Lange did a great job, but not for this low level of sophistication!

[Kiyoshi Takeuchi · Rating 5 out of 5]

The chapters on field and Galois theory are what distinguish this book from others.

[Jingyuan · Rating 4 out of 5]

good but hard to understand text, syntax and notation is a bit weird for modern standards.

i believe lang's purpose in writing this book was to emphasize his superiority to mathematics graduate students. mission accomplished. read it if you already know everything in it, or if you enjoy hieroglyphics.

[Tim · Rating 3 out of 5]

as far as Lang goes, it's not bad, that is to say, this book would be horrible to learn from but as a reference, it's pretty decent.

good stuff, i didn't read it like a novel though, i just used as a reference book, i enjoyed it
