On the Genus of the Co-Annihilating Graph of Commutative Rings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
Let R be a commutative ring with identity and 𝒰R be the set of all nonzero non-units of R. The co-annihilating graph of R, denoted by 𝒞𝒜R, is a graph with vertex set 𝒰R and two vertices x and y are adjacent whenever ann(x) ∩ ann(y) = (0).

Hopfian additive groups of rings [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
A group is called Hopfian  if it is not isomorphic to any of its proper factor groups, or, equivalently, any of its epimorphisms on itself is an isomorphism, i.e., an automorphism. This property was first proved by the Swiss mathematician H.

VNR rings, $\Pi$-regular rings and annihilators [PDF]

open access: yes, 1974
summary:Von Neumann regular rings, hereditary rings, semi-simple Artinian rings, self-injective regular rings are characterized. Rings which are either strongly regular or semi-simple Artinian are considered.

On the mapping xy→(xy)n in an associative ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We consider the following condition (*) on an associative ring R:(*). There exists a function f from R into R such that f is a group homomorphism of (R,+), f is injective on R2, and f(xy)=(xy)n(x,y) for some positive integer n(x,y)>1. Commutativity and

Noetherian and Artinian ordered groupoids—semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Chain conditions, finiteness conditions, growth conditions, and other forms of finiteness, Noetherian rings and Artinian rings have been systematically studied for commutative rings and algebras since 1959.

SIMPLE AND SEMI-SIMPLE ARTINIAN RINGS [PDF]

open access: yes, 2017
The main purpose of this paper is to examine the road towards the structure of simple and semi-simple Artinian rings. We refer to these structure theorems as the Wedderburn-Artin theorems. On this journey, we will discuss R-modules, the Jacobson radical,

Subrings of I-rings and S-rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
Let R be a non-commutative associative ring with unity 1≠0, a left R-module is said to satisfy property (I) (resp. (S)) if every injective (resp. surjective) endomorphism of M is an automorphism of M.

Trivial Extension of π-Regular Rings [PDF]

open access: yesEngineering and Technology Journal, 2016
In this paper we investigate if it is possible that the trivial extension ring T(R,R) inherit the properties of the ring R and present the relationship between the trivial extension T(R,M) of a ring R by an R-module M and theπ-regularity of Rby taking ...

Topologically left artinian rings

open access: yesJournal of Algebra, 1985
In this paper are considered linearly topologized rings with identity all whose factor-modules at open left ideals are artinian (TA-rings). In the characterization of TA-rings an important role is played by a minimal cogenerator \({}_ RV\) of the class of \(R\)-torsion left \(R\)-modules. Some results about structure and features of the module \({}_ RV\
