Intro to Abstract Algebra by Paul Garrett 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.
Abstract Algebra by John A. Beachy, William D. Blair
They come in a nice mix from easy computations to warm the students up to more difficult theoretical problems. Contents Chapter 1 Integers. This online text contains many of the definitions and theorems from the area of mathematics generally called abstract algebra. Recognizes the developing maturity of students by raising the writing level as the book progresses.
We view these chapters as studying cyclic groups and permutation groups, respectively. We have also benefitted over the years from numerous comments from our own students and from a variety of colleagues. It contains solutions to all exercises.

The text emphasizes the historical connections to the solution of polynomial equations and to the theory of numbers. Chapter 5 contains basic facts about commutative rings, and contains many examples which depend on a knowledge of polynomial rings from Chapter 4.
There are enough good ones to make it possible to use the book several semesters in a row without repeating too much. 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. Chapter 5 also depends on Chapter 3, since we make use of facts about groups in the development of ring theory, particularly in Section 5. Provides chapter introductions and notes that give motivation and historical context while tying the subject matter in with the broader picture.

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. The authors introduce chapters by indicating why the material is important and, at the same time, relating the new material to things from the students background and linking the subject matter of the chapter to the broader picture.
Rather than spending a lot of time on axiomatics and serious theorem proving, the author wanted to spend more time with examples, simple applications and with making scenic detours. 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.
For example, cyclic groups are introduced in Chapter 1 in the context of number theory, and permutations are studied in Chapter 2, before abstract groups are introduced in Chapter 3. Many nice examples, as well as good theorems often omitted from undergraduate courses.
It reads as an upper-level undergraduate text should. Chapter 7 Structure of Groups. We use the book in a linear fashion, but there are some alternatives to that approach. 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.
Supplementary material for instructors and students available on the books Web site: Introduction to Abstract Algebra by D. Beachy and William D. I like this balance very much. Account Options Sign in.

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.
With students who already have some acquaintance with the material in Chapters 1 and 2, it would be possible to begin with Chapter 3, on groups, using the first two chapters for a reference. Click here for information about the Second Editionincluding the appropriate Study Guide.
Sen – Creighton University This book is intended for a one-year introductory course in abstract algebra with some topics of an advanced level. The exercises are the main reason I am interested in this book.
We would like to point out to both students and instructors that there is some supplementary material available on the book’s website. Includes such optional topics as finite fields, the Sylow theorems, finite abelian groups, the simplicity of PSL 2 FEuclidean domains, unique factorization domains, cyclotomic polynomials, arithmetic functions, Moebius inversion, quadratic reciprocity, primitive roots, and diophantine equations.
Finally, we would like to thank our publisher, Neil Rowe, for his continued support of our writing. Request Faculty Examination Copy. A number theory thread runs throughout several optional sections, and there is an overview of techniques for computing Galois groups.
