• Preface. Preliminaries. Basic general constructions of rings and modules. Homological dimensions of rings and modules. Goldie and Krull dimensions of rings and modules. Rings with Finiteness conditions. Krull-Remak-Schmidt-Azumaya theorem. Hereditary and semihereditary rings. Serial nonsingular rings. Jacobson's conjecture. Rings related to Finite posets. Distributive and semidistributive rings. The group of extensions. Modules over semiperfect rings. Representations of primitive posets. Representations of quivers, species and finite dimensional algebras. Artinian rings of finite representation type. Semiperfect rings of bounded representation type.

Rings, which play a fundamental role in analysis, geometry, and topology, constitute perhaps the most ubiquitous algebraic structures across mathematics. Starting with fields (the most familiar rings), considering polynomials leads to commutative rings and considering matrices leads to non-commutative algebra. The present volume, though lacking a number, joins a series now spread over three publishers. Like volumes 1 and 2, it surveys aspects of non-commutative rings (volume 3 went in another direction) but stands self-contained, despite the occasional reference to previous volumes. Progress in ring theory depends on conditions designed to isolate special classes of rings admitting satisfying structure theorems. Each chapter surveys such conditions and their consequences: hereditary rings, valuation domains, nonsingular rings, Goldie rings, FDI-rings, exchange rings, Rickart rings, serial nonsingular rings, and many more. Commutative ring concepts tend to have diverse, but limited, generalizations in the non-commutative context, and the early chapters particularly explore such themes. The authors supply complete details, even for simple arguments that other authors might package into exercises (of which this book has none), making the book an excellent reference. Readers will find all developments digested into small satisfying steps, with major results seeming to drop out effortlessly.--D. V. Feldman, University of New Hampshire, Appeared in February 2017 issue of CHOICE
