Rings over which flat covers of finitely generated modules are projective

A Amini, M Ershad, H Sharif - Communications in Algebra, 2008 - Taylor & Francis
In Bican et al., it is proved that all modules over an arbitrary ring have flat covers. In this
article, we shall study rings over which flat covers of finitely generated modules are …

Flat modules and lifting of finitely generated projective modules

A Facchini, D Herbera, I Sakhajev - Pacific journal of mathematics, 2005 - msp.org
We introduce nets in rings, which turn out to describe right flat modules and left flat modules
over a fixed ring R at the same time. As an application we prove that for a finitely generated …

On finitely generated flat modules

S Jøndrup - Mathematica Scandinavica, 1970 - JSTOR
In this note we shall consider rings A with the property that any flat and finitely generated A-
module is projective, and we will prove that this class of rings is rather big. If we require that …

[PDF][PDF] On rings over which every flat left module is finitely projective

Z Shenglin - Journal of Algebra, 1991 - core.ac.uk
In [3], Bass has shown that a ring R is left perfect if and only if every flat left R-module is
projective and if and only if R satisfies the descending chain condition on principal right …

[PDF][PDF] On flat and projective envelopes

JA Mayor, JM Hernandez - Journal of algebra, 1993 - core.ac.uk
All the rings will be associative with identity and the modules will be unital. If M is a right
module we denote by M* the dual module Hom „(M., R) of M. If M is a right R-module, a flat …

On finitely generated flat modules

WV Vasconcelos - Transactions of the American Mathematical Society, 1969 - JSTOR
Introduction. The aim of this paper is to study conditions which reflect the projectivity of a
given finitely generated flat module over a commutative ring. The use of the invariant factors …

𝑝. 𝑝. rings and finitely generated flat ideals

S Jøndrup - Proceedings of the American Mathematical Society, 1971 - ams.org
In this note all rings considered are associative with an identity element 1 and all modules
are unital left modules. It is shown that a commutative ring $ R $ has principal ideals …
