Introduction to Ring Theory springer.com Mathematics : Algebra Cohn, Paul M. Introduction to Ring Theory Paul Cohn is a well-known expositor and expert in the field This book follows on from the SUMS book "Groups, Rings and Fields" by David Wallace Most parts of algebra have undergone great changes and advances in recent years, perhaps none more so than ring theory. In this volume, Paul Cohn provides a clear and structured introduction to the subject. After a chapter on the definition of rings and modules there are brief accounts of Artinian rings, commutative Noetherian rings and ring constructions, such as the direct product. Tensor product and rings of fractions, followed by a description of free rings. The reader is assumed to have a basic understanding of set theory, group theory and vector spaces. Over two hundred carefully selected exercises are included, most with outline Springer solutions. 2000, X, 229 p. 1st Order online at springer.com/booksellers edition Springer Nature Customer Service Center LLC 233 Spring Street New York, NY 10013 Printed book USA Softcover T: +1-800-SPRINGER NATURE (777-4643) or 212-460-1500 Printed book [email protected] Softcover ISBN 978-1-85233-206-8 $ 44,99 Available Discount group Professional Books (2) Product category Undergraduate textbook Series Springer Undergraduate Mathematics Series Other renditions Softcover ISBN 978-1-4471-0476-6 Prices and other details are subject to change without notice.

  • Noncommutative Localization in Group Rings 3
    NONCOMMUTATIVE LOCALIZATION IN GROUP RINGS PETER A. LINNELL Abstract. This paper will briefly survey some recent methods of localiza- tion in group rings, which work in more general contexts than the classical Ore localization. In particular the Cohn localization using matrices will be described, but other methods will also be considered. 1. Introduction Let R be a commutative ring and let S = {s ∈ R | sr 6= 0 for all r ∈ R \ 0}, the set of non-zerodivisors of R. Then, as in the same manner one constructs Q from Z, we can form the quotient ring RS−1 which consists of elements of the form r/s with r ∈ R and s ∈ S, and in which r1/s1 = r2/s2 if and only if r1s2 = s1r2. We can consider R as a subring RS−1 by identifying r ∈ R with r/1 ∈ RS−1. Then RS−1 is a ring containing R with the property that every element is either a zerodivisor or invertible. Furthermore, every element of RS−1 can be written in the form rs−1 with r ∈ R and s ∈ S (though not uniquely so). In the case R is an integral domain, then RS−1 will be a field and will be generated as a field by R (i.e. if K is a subfield of RS−1 containing R, then K = RS−1). Moreover if K is another field containing R which is generated by R, then K is isomorphic to RS−1 and in fact there is a ring isomorphism RS−1 → K which is the identity on R.
