Abstract Algebra – John A. Beachy, William D. Blair – Google Books

Makes a concerted effort throughout to develop key examples in detail before introducing the relevant abstract definitions. Request Faculty Examination Copy.

Third Edition John A. Recognizes the developing maturity of students by raising the writing level as the book progresses. 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.

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

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.

Rather than outlining absstract 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 caution in choosing any paths other than the ones we have suggested above. For strong classes, there is a complete treatment of Galois theory, and for honors students, there are optional sections on advanced number theory topics.


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. It reads as an upper-level undergraduate text should. 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.

We view these chapters as studying cyclic groups and permutation groups, respectively. Waveland PressJan 5, – Mathematics – pages. This online text contains many of the definitions and theorems from the area of mathematics brachy called abstract algebra. Separating the two hurdles of devising proofs and grasping abstract mathematics makes abstract algebra more accessible.

They come in a nice mix from easy computations to warm the students up to more difficult theoretical problems. FEATURES Progresses students from writing proofs in the familiar setting of the integers to dealing with abstract concepts once they have an some confidence.

Selected pages Title Page. Sen – Creighton University This book is intended for a one-year introductory course in abstract algebra with some topics of an advanced level.

We would like to add Doug Bowman, Dave Rusin, and Jeff Thunder to the list of colleagues given in the preface to the second edition.

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. Blair Snippet view – Chapter 8 Galois Theory. After covering Chapter 5, it is possible to go directly to Chapter 9, which has more ring theory and some slgebra to number theory. With students who already have some acquaintance with the material in Chapters 1 and 2, it would be beadhy to begin with Chapter 3, on groups, using the first two chapters for a reference.

We believe that our responses to his suggestions and corrections have measurably improved the book. 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.

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. After using the book, on more than one occasion he sent us a large number of detailed suggestions on how to improve the presentation. Abstract Algebra by John A. The book offers an extensive set of exercises that help to build skills in writing proofs. We would like to point out to both students and instructors that there is some supplementary material available on the book’s website.

Abstract Algebra I by Marcel B. Finan – Arkansas Tech University Contents: We would also like to acknowledge important corrections and suggestions that we received from Marie Vitulli, of the University of Oregon, and from David Doster, of Choate Rosemary Hall.
