Assuming a modest knowledge of abstract algebra taught in a standard first-year graduate course, this textbook gives a general introduction to the theory of rings. Consisting of eight chapters, it begins with the classical Wedderburn-Artin theory of semisimple rings (Chapter 1), and then deals with Jacobson’s general theory of the radicals for rings possibly without any chain conditions (Chapter 2). After a pleasant excursion into the rudiments of representation theory (Chapter 3), the author resumes his course with prime and primitive rings (Chapter 4), keeping with division rings (Chapter 5), ordered rings (Chapter 6), local and semilocal rings (Chapter 7), and finally ending up with perfect and semiperfect rings (Chapter 8). Such topics as the detailed exposition of the Mal’cev-Neumann construction of general Laurent series rings given here are not easily available in other standard textbooks on ring theory. The intended second volume will probably cover the theory of modules, rings of quotients, rings with polynomial identities, the structure theory of finite-dimensional central simple algebras, etc.
