Classifications of Several Classes of Armendariz-like Rings Relative to an Abelian Monoid and Its Applications

open access: yesMathematics
Let M be an Abelian monoid. A necessary and sufficient condition for the class ArmM of all Armendariz rings relative to M to coincide with the class Arm of all Armendariz rings is given.

Fractional skew monoid rings [PDF]

open access: yesJournal of Algebra, 2004
Given an action of a monoid $T$ on a ring $A$ by ring endomorphisms, and an Ore subset $S$ of $T$, a general construction of a fractional skew monoid ring $S^{\rm op} * A * T$ is given, extending the usual constructions of skew group rings and of skew semigroup rings.

PRIME RADICALS IN UP-MONOID RINGS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2012
A monoid \(G\) is a `unique product monoid' (up-monoid) if for any two nonempty finite subsets \(A\) and \(B\) of \(G\), there is at least one \(c\in G\) which has a unique representation as \(c=ab\) with \(a\in A\) and \(b\in B\). Here the authors study the relationships between nil-related properties of a ring and those of the monoid ring \(RG ...

Nil-Armendariz Rings Relative to a Monoid

open access: yesMediterranean Journal of Mathematics, 2012
The notion of an Armendariz ring has been generalized in many different ways. Here another generalization is presented. For a monoid \(M\), \(R[M]\) is the monoid ring over \(R\) and \(\text{nil}(R)\) is the set of nilpotent elements of \(R\). A ring \(R\) is called `nil-Armendariz relative to \(M\)' if whenever \(\alpha=\sum_{i=1}^na_ig_i,\beta=\sum_ ...

Galois orders in skew monoid rings

open access: yesJournal of Algebra, 2010
The paper deals with ring extensions \(\Gamma\subset U\) of an integral domain \(\Gamma\), in particular, a general class of subrings of invariants in twisted Galois semigroup rings which the authors call Galois orders. The study of such Galois orders is inspired by the authors' previous work on Harish-Chandra categories [Fibers of characters in Harish-

Endo-Noetherian Skew Generalized Power Series Rings [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2023
Endo-Noetherian modules were introduced by A. Kaidi and E. Sanchez] as a generalization of Noetherian modules. A left Ɍ-module M which satisfies the ascending chain condition for endomorphic kernels is said to be endo-Noetherian.

The Ring Homomorphisms of Matrix Rings over Skew Generalized Power Series Rings

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2021
Let  M_n (R_1 [[S_1,≤_1,ω_1]]) and M_n (R_2 [[S_2,≤_2,ω_2]]) be a matrix rings over skew generalized power series rings, where R_1,R_2 are commutative rings with an identity element, (S_1,≤_1 ),(S_2,≤_2 ) are strictly ordered monoids, ω_1:S_1→End(R_1 ),〖

SOLVING DIFFERENCE EQUATIONS IN SEQUENCES: UNIVERSALITY AND UNDECIDABILITY

open access: yesForum of Mathematics, Sigma, 2020
We study solutions of difference equations in the rings of sequences and, more generally, solutions of equations with a monoid action in the ring of sequences indexed by the monoid. This framework includes, for example, difference equations on grids (for

On the Monoid of Unital Endomorphisms of a Boolean Ring [PDF]

open access: yesAxioms, 2021
Let X be a nonempty set and P(X) the power set of X. The aim of this paper is to provide an explicit description of the monoid End1P(X)(P(X)) of unital ring endomorphisms of the Boolean ring P(X) and the automorphism group Aut(P(X)) when X is finite. Among other facts, it is shown that if X has cardinality n≥1, then End1P(X)(P(X))≅Tnop, where Tn is the

On Crossed Product Rings Over p.q.-Baer and Quasi-Baer Rings

open access: yesInternational Journal of Analysis and Applications, 2023
In this paper, we consider a ring R and a monoid M equipped with a twisting map f: M×M -> U(R) and an action map ω: M -> Aut(R). The main objective of our study is to investigate the conditions under which the crossed product structure R⋊M is p.q.-Baer ...
