This volume provides a comprehensive introduction to module theory and the related part of
ring theory, including original results as well as the most recent work. It is a useful and …

Continuous and discrete modules are, essentially, generalizations of infective and projective
modules respectively. Continuous modules provide an appropriate setting for decomposition …

This book has two predominant objectives. On the one hand, the fundamental concepts of
the theory of modules and rings are presented, for which the presentation is set out in detail …

Extending modules are generalizations of injective modules and, dually, lifting modules
generalize projective supplemented modules. There is a certain asymmetry in this duality …

Mit diesem Buch werden vor allem zwei Ziele angestrebt. Einmal sollen die Grundbegriffe
der Theorie der Moduln und Ringe dargestellt werden. Dabei ist die Darstellung so …

H-rings and Co-H-rings have been defined by K. Oshiro in [9]. A ring R is a right H-ring (Co-
H-ring) iff every injective (projective) right R-module is lifting (extending). A right H-ring or a …

FiModÄ—> ModZ (wir schreiben den Funktor stets auf die Seite der Skalarmultiplikation). Ist
SMR ein Bimodul, so ist MU ein S-Untermodul von M. Wie üblich erklärt man Inklusion …

We call a module Malmost perfect if every M-generated flat module is M-projective. Any
perfect module is almost perfect. We characterize almost-perfect modules and investigate …
