Introduction to Abstract Algebra

Text in English. 327 pp. Stain on the front cover. Faint Scratching. No markings. Taking a slightly different approach from similar texts, Introduction to Abstract Algebra presents abstract algebra as the main tool underlying discrete mathematics and the digital world. It helps readers fully understand groups, rings, semigroups, and monoids by rigorouslybuilding concepts from first principles The book begins with a quick introduction to algebra, providing a foundation to exhibit irrational numbers and gain an appreciation of cryptography. It then covers all the basics of abstract algebra, including groups, homomorphisms, rings, and fields. The final chapters deal with more advanced topics, such as factorization, modules, group actions and quasigroups. Study projects at the end of each chapter encompass a range of applications, offering additional opportunities for research. Features Looks at abstract algebra as the main tool underlying discrete mathematics and the digital world Uses semigroups and monoids as stepping stones to present the concepts of groups and rings Presents the fundamentals of abstract algebra, before offering deeper coverage of group and ring theory Provides examples of abstract algebra concepts in matrices and calculus Contains numerous exercises of varying levels of difficulty, chapter notes that point out variations in notation and approach, and study projects that cover an array of applications and developments of the theory.…
