The category of all modules over a general associative ring is too complex to admit any reasonable classification. Thus, unless the ring is of finite representa

This monograph- now in its second revised and extended edition- provides a thorough treatment of module theory, a subfield of algebra. The authors develop an ap

This book offers a comprehensive account of not necessarily commutative arithmetical rings, examining structural and homological properties of modules over arit
