Second modules over noncommutative rings
Let R be an arbitrary ring. A nonzero unital right R-module M is called a second module if M
and all its nonzero homomorphic images have the same annihilator in R. It is proved that if R …

FP-PROJECTIVE DIMENSIONS
L Mao, N Ding - Communications in Algebra®, 2005 - Taylor & Francis
We define a dimension, called an FP-projective dimension, for modules and rings. It
measures how far away a finitely generated module is from being finitely presented, and …

Notes on cotorsion modules
L Mao, N Ding - Communications in Algebra®, 2005 - Taylor & Francis
Let R be a ring. A right R-module C is called cotorsion if for any flat right R-module biF. In
this paper, we first give some results on cotorsion envelopes that are analogous to those on …

Noncommutative generalizations of theorems of Cohen and Kaplansky
ML Reyes - Algebras and Representation theory, 2012 - Springer
This paper investigates situations where a property of a ring can be tested on a set of “prime
right ideals.” Generalizing theorems of Cohen and Kaplansky, we show that every right ideal …

Cotorsion modules and relative pure-injectivity
L Mao, N Ding - Journal of the Australian Mathematical Society, 2006 - cambridge.org
Let R be a ring. A right R-module C is called a cotorsion module if Ext1R (F, C)= 0 for any flat
right R-module F. In this paper, we first characterize those rings satisfying the condition that …

Neat-flat modules
E Büyükaşık, Y Durğun - Communications in Algebra, 2016 - Taylor & Francis
Let R be a ring. A right R-module M is said to be neat-flat if the kernel of any epimorphism
Y→ M is neat in Y, ie, the induced map Hom (S, Y)→ Hom (S, M) is surjective for any simple …
