Faithfully exact functors and their applications to projective modules and injective modules
T Ishikawa - Nagoya Mathematical Journal, 1964 - cambridge.org
The aim of this paper is to study a property of a special kind of exact functors and give some
applications to projective modules and injective modules. In section 1 we introduce the …

Static modules and equivalences
R Wisbauer - LECTURE NOTES IN PURE AND APPLIED …, 2000 - books.google.com
By a well known theorem of K. Morita, any equivalence between full module categories over
rings R and S, are given by a bimodule RPS, such that RP is a finitely generated projective …

Tilting preenvelopes and cotilting precovers in general Abelian categories
We consider an arbitrary Abelian category A and a subcategory T closed under extensions
and direct summands, and characterize those T that are (semi-) special preenveloping in A; …

Extension functors of local cohomology modules
Let $ R $ be a commutative Noetherian ring with non-zero identity, $\fa $ an ideal of $ R $,
and $ X $ an $ R $--module. In this paper, for fixed integers $ s, t $ and a finite $\fa $--torsion …

Absolutely pure modules
KR Pinzon - 2005 - uknowledge.uky.edu
Absolutely pure modules act in ways similar to injective modules. Therefore, through-out this
document we investigate many of these properties of absolutely pure modules which are …
