Modules over endomorphism rings

AK Gupta, K Varadarajan - Communications in Algebra, 1980 - Taylor & Francis
IYTRODCCTION 1: n~ onorphism rings of various types of modules have been objects of
extensive study in the recent past [2, 11, 14, 15, 18, 25, 261. In [15] Erika Mares introduced …

Cancellation modules over regular rings

(Sketch). is done. If R has stable range 1 then, by a theorem of Kaplansky [16, 4.7], the same
is true for the endomorphism ring of any finitely generated projective R-module. So R unit …

Generalized uniserial rings

YA Drozd - Mathematical notes of the Academy of Sciences of the …, 1975 - Springer
The following conditions are shown to be equivalent: 1) ring A is generalized uniserial (not
necessarily artinian); 2) every finitely presented A module is semiserial; 3) A is semiperfect …

The structure of extending modules over Noetherian rings

MA Kamal, BJ Müller - 1988 - projecteuclid.org
A module is said to be extending, if every closed (ie complement) submodule is a direct
summand. This property is usually denoted by (Q). It is, obviously, equivalent to the …

Modules with the summand intersection property

J Hausen - Communications in Algebra, 1989 - Taylor & Francis
The (unital right) module M (over the ring R with identity) is said to have the summand
intersection property if the intersection of any two direct summands of M is a direct …

Quasi-projective and quasi-injective modules

A Koehler - Pacific J. Math, 1971 - msp.org
M commutes. The first section of this paper contains results which are needed to prove a
decomposition theorem for quasi-projective modules over left perfect rings (Theorem 1.10) …

[PDF][PDF] ∑-injective modules

I Beck - Journal of Algebra, 1972 - core.ac.uk
Some theorems in [4] indicate that the injective modules over a ring R provide a great deal of
information about the structure of the ring. More recently, the papers of H. Bass [9] and C …

Coproducts and some universal ring constructions

GM Bergman - Transactions of the American Mathematical Society, 1974 - ams.org
Let $ R $ be an algebra over a field $ k $, and $ P, Q $ be two nonzero finitely generated
projective $ R $-modules. By adjoining further generators and relations to $ R $, one can …

Injective hulls of torsion free modules

J Zelmanowitz - Canadian Journal of Mathematics, 1971 - cambridge.org
In § 1, we begin with a basic theorem which describes a convenient embedding of a
nonsingular left R-module into a complete direct product of copies of the left injective hull of …
