In this paper, we define weakly coherent rings, and examine the transfer of these rings to homomorphic image, trivial ring extension, localization, and direct product. These results provide examples of weakly coherent rings that are not coherent rings. We show that the class of weakly coherent rings is not stable by localization. Also, we show that the class of weakly coherent rings and the class of strongly 2-coherent rings are not comparable.

WEAKLY COHERENT PROPERTY IN AMALGAMATED
called the amalgamation of A and B along J with respect to f (introduced and studied by D’Anna, Finocchiaro, and Fontana in [9, 10]). This constuction is a generalization of the amalgamated

On 2-von Neumann Regular Rings
In this article, we consider 2-von Neumann regular rings, that is, rings R with the property that, if F 2 → F 1 → F 0 → E → 0 is an exact sequence of R-modules with F 0, F 1, and F 2 finitely
Trivial Extensions Defined by Coherent-like Conditions
Abstract This paper investigates coherent-like conditions and related properties that a trivial extension R ≔ A ∝ E might inherit from the ring A for some classes of modules E. It captures previous
Trivial Extensions of Local Rings and a Conjecture of Costa
This paper partly settles a conjecture of Costa on (n,d)-rings, i.e., rings in which n-presented modules have projective dimension at most d. For this purpose, a theorem studies the transfer of the

An Introduction to Homological Algebra
An Introduction to Homological Algebra discusses the origins of algebraic topology. It also presents the study of homological algebra as a two-stage affair. First, one must learn the language of Ext
Non Commutative Algebra
We have seen (p. 62) how the first non commutative algebras made their appearance in 1843–44, in the work of Hamilton [145 a] and of Grassmann ([134], v. I2). Hamilton, in introducing the
