This volume consists mainly of refereed papers and surveys presented at the 1994 Padova Conference "Abelian Groups and Modules". Linking three main areas in algebra, namely Abelian groups, commutative algebra and modules over non-commutative rings, this work surveys current trends as well as recent results in specific research topics. Subjects covered include: representation theory, Hopf modules, Krull dimension, dualities, finitistic dimension, algebraically compact modules, von Neumann regular rings, serial rings, reflexive algebras, endomorphism rings, Butler groups, torsion-free Abelian groups, and totally projective groups.
