Let R be a ring, G a group of automorphisms of R and RG the fixed subring of G on R. In [8],
Jondrup studied when R is projective as a right Rc-module. The first aim of this paper is to …

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 …

One can try to generalize this result to (unital left) modules A over a ring with 1, by replacing
torsion-freeness and freeness by flatness and projectivity, respectively. One naturally …

Let R and S be arbitrary rings, RM and SN countably generated free modules, and let φ: End
(RM)→ End (sN) be an isomorphism between the endomorphism rings of M and N. Camillo …

A module M is said to be weakly N-projective if it has a projective cover π: P (M)↠ M and for
each homomorphism: P (M)→ N there exists an epimorphism σ: P (M)↠ M such that (kerσ) …

The object of this paper is to study the relationship between certain projective modules and
their endomorphism rings. Specifically, the basic problem is to describe the projective …

Over a ring A let PA be a finitely generated projective right A-module with A-endomorphism
ring B. Anderson has called PA an injector, perfect injector, projector, perfect projector, if the …
