Y Durğun - Hacettepe Journal of Mathematics and Statistics, 2022 - dergipark.org.tr
A p-indigent module is one that is subprojective only to projective modules. An RD-
projective module is subprojective to any torsionfree (and flat) module. An RD-projective …

Rings Whose Pure-Projective Modules Have Maximal or Minimal Projectivity Domain
Z Türkoğlu - Journal of New Theory, 2024 - dergipark.org.tr
In this study, we investigate the projectivity domain of pure-projective modules. A pure-
projective module is called special-pure-projective (s-pure-projective) module if its …

Precover completing domains and approximations
In this paper, we introduce an X-precover completing domain X− 1 (L), with L being a class
of modules and not necessarily a single module, and then investigate when every module in …

On subinjectivity domains of RD-injective modules
Y Durğun - Asian-European Journal of Mathematics, 2022 - World Scientific
The subjectivity domain of a module allows us to evaluate how close (or far) a module is
from being injective. In this paper, we consider three families of rings characterized by their …

[引用][C] Projectivity and subprojectivity domains in exact categories
S Crivei, R Pop - Journal of Algebra and Its Applications, 2023 - World Scientific
We generalize to exact categories some new perspectives on projectivity, which allow us to
unify a series of recent concepts from module categories or abelian categories and to obtain …
