Introduction to Abstract Algebra
Neil McCoy, Gerald Janusz
A revision of McCoy's classic text, Introductory Abstract Algebra, Sixth Edition, retains the goals of earlier editions by providing the key information for a first course in abstract algebra in an easily understood, digestible manner. The material in the sixth edition is kept at approximately the same level as that in the previous editions with a number of comments, remarks, and exercises that point students toward more advanced topics. Rings are presented before groups because the ring of integers is already known to students and easily serves as a source of examples.
Rings. Congruences. Integral Domains and Fields. Factorization. Polynomials. Groups. Finite Abelian Groups. Finite Groups. Additional Topics.
