Flatness and f-projectivity of torsion-free modules and injective modules
MF Jones - Advances in Non-Commutative Ring Theory …, 2006 - Springer
Let Rbe a ring with identity. Chase [5] has characterized the right coherent rings; he has
shown that arbitrary products of RR are flat if and only if finitely generated submodules of …

Flat-precover completing domains
H Amzil, D Bennis, JR García Rozas… - Quaestiones …, 2023 - Taylor & Francis
Recently, many authors have embraced the study of certain properties of modules such as

Dual modules, f-projective modules and Π-coherence over trivial ring extensions
L Mao - Communications in Algebra, 2024 - Taylor & Francis
Abstract Let R⋉ M be a trivial extension of a ring R by an RR-bimodule M. We first describe
explicitly the structure of a dual module over R⋉ M. Then we characterize Mittag-Leffler …

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 …

When every finitely projective ideal is projective
N Mahdou, S Moussaoui, MAS Moutui - Indian Journal of Pure and Applied …, 2022 - Springer
This paper studies the class of rings in which every finitely projective ideal is projective (FPP-
ring for short). We examine the transfer of this property to various context of commutative ring …
