Mac Lane had had much more teaching experience than I, and I think the popularity of our book owes more to him than to me. The most striking characteristic of modern algebra is the deduction of the theoretical properties of such formal systems as groups, rings, fields, and vector spaces. I do not think using algebras is a problem, but three whole chapters is probably a bit much, so some would have to be cut.

Much of this significance, it seems to us, lies in the imaginative appeal of the subject. Our collaboration involved some compromises. The original comprehensive Survey has been reordered somewhat and augmented to the extent of approximately fifty pages.

I think you could cover the entire book, minus perhaps Chapter XIV on lattices, which are not typically emphasized and are partly historical, and possibly Chapter VIII, which is a bit odd, in my opinion. However, as soon as one introduces actual axioms that constrain the operators this is no longer trueâ€”and in general it can be undecidable whether or not a particular equivalence holds.

Some people mistakenly believe they cannot. It has a lot of linear algebra, which is good, and it is not too hard, but it requires some work. Marsden George C. It also introduces the student to modules, but it does not insist on birkhofv with modules instead of vector spaces whenever possible, which is probably good, because modules hirkhoff serve to slightly confuse without adding anything more than a bit of generality.

One of the best things about this book is the balanced approach to rigour and abstractness in relation to intuitive appreciation and concrete application. I think graduate courses should use category theory pretty openly.

This is not to say Mac Lane and Birkhoff do this! For maclqne, we obviously need to ensure they see examples, learn the basic theory, be able to write proofs, etc. Judson is good all around.

Other more minor changes and additions helped to increase its popularity, with annual sales in the range 14, As Mac Lane did years ago, it is best to supplement the text with something easier, something intended for undergraduates. Moreover, it was written in a clear and enthusiastic style that conveyed to the reader an appreciation of the aesthetic character of the subject as well as its rigour and power.

Finally, the last three chapters provide an introduction to general commutative algebra and arithmetic: I have come to like Gallian quite a bit since first giving maclans a real chance to see what my birkhovf teaches. This is a text on modern algebra that is particularly suited for a first year graduate course or for an advanced undergraduate course. Algebra was almost unheard of at the undergraduate level not too long ago, whereas now an undergraduate program would be remiss not to require students take at least an introductory course covering the basic theories of groups, rings, and fields.

Chapter 6 introduces noncommutative algebra through its simplest and most fundamental concept: Terminology and notation which has become outmoded since the Revised Edition was published in have been brought up-to-date; material on Boolean algebra and lattices has been completely rewritten; an introduction to tensor products has been added; numerous problems have been replaced and many new ones added; and throughout the book are hundreds of minor revisions to keep the work in the forefront of modern algebra literature and pedagogy.

This independence is intended to make the birmhoff useful not only for a full-year course, assuming only high-school algebra, but also for various shorter courses. He is best known for his work in lattice theory. Again, eventually the students should be given this stuff to them. Some material, especially that on linear algebra, has been maclzne in the light of experience. Garrett and I combined our preliminary notes to publish with MacMillan in our joint book, Survey of Modern Algebra.

We have done this by illustrating each new term by as many familiar examples as possible. There are still many overqualified students and many underqualified students, and I can provide a constructive proof of that fact. The authors are quick to indicate applications and careful to motivate and illustrate abstractions. The lecture ought to focus on the main ideas, examples, and results, and the book birkhpff to clearly show what is important, very important, etc. Although two or three books on the new algebra have already appeared in English, the present volume appears to the reviewer to be the best all-round introduction to the subject, unique in its clarity, balance, generality and inclusiveness.

Then and later we took part in the flow of new ideas from discovery to use and to present to students. Birkhoff held no Ph. Although my course was well attended, I was much more research-oriented than teaching-oriented. Adding in some applications may be good, too; I do not remember many being in Mac Lane. Accordingly, we have tried throughout to express the conceptual background of the various definitions used.

A section on bilinear forms and tensor products has been added to the chapter 7 on vector spaces, while Chapter 11, now entitled “Boolean algebras and lattices”, contains a new introduction to Boolean algebras, as well as a section on the representation of such by sets.

Also,the author writes very well indeed.

Theoretically, less-prepared students and more-prepared students would not only survive but also get from this something substantial. Post as a guest Name. Our third edition, infinally included tensor products of vector spaces, while the fourth edition clarified the treatment of Boolean algebras and lattices.

These theorems are then applied to some familiar and to some less familiar examples, thus broadening the student’s viewpoint without getting him lost in abstractions. Chapters give an introduction to the theory of linear and polynomial equations in commutative rings.

Extending the results of Young, the Birkhoff-Varga collaboration led to many publications on positive operators and iterative methods for p -cyclic matrices.
