In this edition we have added about exercises, we have added 1 to all rings, and we have done our best to weed out various errors and misprints.

We believe that our responses to his suggestions and corrections have measurably improved the book. Blair Snippet view – We give a rigorous treatment of the fundamentals of abstract algebra with numerous examples to illustrate the concepts. It reads as an upper-level undergraduate text should.

The first two chapters on the integers and functions contain full details, in addition to comments on techniques of proof. They come in a nice mix from easy computations to warm the students up to more difficult theoretical problems. Abstract Algebra I by Marcel B. Makes a concerted effort throughout to develop key examples in detail before introducing the relevant abstract definitions.

### Waveland Press – Abstract Algebra, Third Edition, by John A. Beachy, William D. Blair

Beachy and Blairs clear narrative presentation responds to the needs of inexperienced students who stumble over proof writing, who understand definitions and theorems but cannot do the problems, and who want more examples that tie into their previous experience. For strong classes, there is a complete treatment of Galois theory, and for honors students, there are optional sections on advanced number theory topics.

They are a great mix of straightforward practice, some applications, and a healthy amount of theory that occasionally dives extra deep. Chapter introductions, together with notes at the ends of certain chapters, provide motivation and historical context, while relating the subject matter to the broader mathematical picture.

Supplementary material for instructors and students available on the books Web site: Instructors will find the latest edition pitched at a suitable level of difficulty and will appreciate its gradual increase in the level of sophistication as the student progresses through the book. Offers an extensive set of exercises that provides ample opportunity for students to develop their ability to write proofs. Chapter 5 contains basic facts about commutative rings, and contains many examples which depend on a knowledge of polynomial rings from Chapter 4.

## Abstract Algebra by John A. Beachy, William D. Blair

Chapter 8 Galois Theory. There are enough good ones to make it possible to use the book several semesters in a row without repeating too much. Our development of Galois theory in Chapter 8 depends on results from Chapters 5 and 6.

Sen – Creighton University This book is intended for a one-year introductory course in abstract algebra with some topics of an advanced level. The ring of integers and rings of polynomials are covered before abstract rings are introduced in Chapter 5. Chapter 9 Unique Factorization. Rather than outlining a large number of possible paths through various parts of the text, we have to ask the instructor to read ahead and use a great deal of abtract in choosing any paths other than the ones we have algrbra above.

The exercises are the main reason I am interested in this book. Read online online html.

BeachyWilliam D. After covering Chapter 5, it is possible to go directly to Chapter 9, which has more ring theory and some applications to number theory. The intermediate chapters on groups, rings, and fields are written at a standard undergraduate level. Intro to Abstract Algebra by Paul Astract The text covers basic algebra of polynomials, induction, sets, counting principles, integers, unique factorization into primes, Sun Ze’s theorem, good algorithm for exponentiation, Fermat’s little theorem, Euler’s theorem, public-key ciphers, etc.

We would like to point out to both students and instructors that there is some supplementary material available on the book’s website. Selected pages Title Page.

Many of these were in response to questions from his students, so we owe an enormous debt of gratitude to his students, as well as to Professor Bergman.

Includes such optional topics as finite fields, the Sylow theorems, finite abelian groups, the simplicity of PSL 2 FEuclidean domains, unique factorization domains, nad polynomials, arithmetic functions, Moebius inversion, quadratic reciprocity, primitive roots, and diophantine equations. The text emphasizes the historical connections to the solution of polynomial equations and to the theory of numbers. Recognizes the developing maturity of students by raising the writing level as the book progresses.

### BEACHY / BLAIR: ABSTRACT ALGEBRA

Account Options Sign in. A number theory thread runs throughout several optional sections, and there is an overview of techniques for computing Galois groups.

BeachyWilliam D. We use the book in a linear fashion, but there are some alternatives to that approach.

With students who already have some acquaintance with the material in Chapters 1 and 2, it would be possible to begin bdachy Chapter 3, on groups, using the first two chapters for a,gebra reference.

Rather than inserting superficial applications at the expense of important mathematical concepts, the Beachy and Blair solid, well-organized treatment motivates the subject with concrete problems from areas that students have previously encountered, namely, the integers and polynomials over the real numbers. Instructors will find the latest edition pitched at a suitable level of difficulty and will appreciate its gradual increase in the level of sophistication as the student progresses through the book.
