The computer projects usually require a knowledge of programming. There are additional exercises or computer projects at the ends of many of the chapters. Many of the more substantial problems require careful thought, so the student should not be discouraged if the solution is not forthcoming after a few minutes of work.

The exercises range in difficulty from very easy to very challenging. Often in the solutions a proof is only sketched, and it is up to the student to provide the details. A section presenting hints and solutions to many of the exercises appears at the end of the text. The nature of the exercises ranges over several categories computational, conceptual, and theoretical problems are included. An exercise set appears at the end of each chapter. This should present no great problem, since most students taking a course in abstract algebra have been introduced to matrices and determinants elsewhere in their career, if they have not already taken a sophomore- or junior-level course in linear algebra.Įxercise sections are the heart of any mathematics text.

Occasionally, we shall assume some basic linear algebra that is, we shall take for granted an elementary knowledge of matrices and determinants. Though there are no specific prerequisites for a course in abstract algebra, students who have had other higher-level courses in mathematics will generally be more prepared than those who have not, because they will possess a bit more mathematical sophistication.

In an applied course, some of the more theoretical results could be assumed or omitted. Hand, if applications are to be emphasized, the course might cover Chapters 1 through 14, and 16 through 22. A two-semester course emphasizing theory might cover Chapters 1 through 6, 9, 10, 11, 13 through 18, 20, 21, 22 (the first part), and 23. Parts of these chapters could be deleted and applications substituted according to the interests of the students and the instructor. A typical one-semester course might cover groups and rings while briefly touching on field theory, using Chapters 1 through 6, 9, 10, 11, 13 (the first part), 16, 17, 18 (the first part), 20, and 21. Emphasis can be placed either on theory or on applications. The order of presentation of topics is standard: groups, then rings, and finally fields. Certainly there is adequate material for a two-semester course, and perhaps more however, for a one-semester course it would be quite easy to omit selected chapters and still have a useful text.

This text contains more material than can possibly be covered in a single semester. Such students often find it hard to see the use of learning to prove theorems and propositions applied examples help the instructor provide motivation. However, one of the major problems in teaching an abstract algebra course is that for many students it is their first encounter with an environment that requires them to do rigorous proofs. Until recently most abstract algebra texts included few if any applications. Though theory still occupies a central role in the subject of abstract algebra and no student should go through such a course without a good notion of what a proof is, the importance of applications such as coding theory and cryptography has grown significantly. However, with the development of computing in the last several decades, applications that involve abstract algebra and discrete mathematics have become increasingly important, and many science, engineering, and computer science students are now electing to minor in mathematics.

Traditionally, these courses have covered the theoretical aspects of groups, rings, and fields. This text is intended for a one- or two-semester undergraduate course in abstract algebra.
