Modern Algebra: An Introduction, 6th Edition

December 2008, ©2009
Modern Algebra: An Introduction, 6th Edition (EHEP000258) cover image


The new sixth edition of Modern Algebra has two main goals: to introduce the most important kinds of algebraic structures, and to help students improve their ability to understand and work with abstract ideas. The first six chapters present the core of the subject; the remainder are designed to be as flexible as possible. The text covers groups before rings, which is a matter of personal preference for instructors.  Modern Algebra, 6e is appropriate for any one-semester junior/senior level course in Modern Algebra, Abstract Algebra, Algebraic Structures, or Groups, Rings and Fields.  The course is mostly comprised of mathematics majors, but engineering and computer science majors may also take it as well.

The Wiley Advantage

  • Durbin takes great care in helping students to understand and work with abstract ideas and proofs in a first course in modern algebra.
  • Each problem set is organized by level of difficulty.  The early problems in each set are grouped in pairs, with solutions to odd-numbered problems in the solutions appendix.
  • The material is arranged so that most of the sections can be covered in one lecture.
  • The flexibility of the text makes it easy for professors to fit the book to their own students and course goals. The first six chapters present the core of the subject, while the subsequent chapters can be determined by individual needs.
  • Sections are short with many examples and explanations, so the students do not feel overwhelmed by the material.
  • Applications are included to help motivate students and to show the usefulness of modern algebra.
