Reversible Rings with Involutions and Some Minimalities [PDF]

open access: yesThe Scientific World Journal, 2013
In continuation of the recent developments on extended reversibilities on rings, we initiate here a study on reversible rings with involutions, or, in short, *-reversible rings. These rings are symmetric, reversible, reflexive, and semicommutative.

RING ENDOMORPHISMS WITH THE REVERSIBLE CONDITION [PDF]

open access: yesCommunications of the Korean Mathematical Society, 2010
P. M. Cohn called a ring R reversible if whenever ab = 0, then ba = 0 for a,b 2 R. Commutative rings and reduced rings are reversible. In this paper, we extend the reversible condition of a ring as follows: Let R be a ring and fi an endomorphism of R, we say that R is right (resp., left) fi-shifting if whenever afi(b) = 0 (resp., fi(a)b = 0) for a,b 2 ...

Reversible group rings

open access: yesJournal of Algebra, 2004
An associative ring \(R\) with identity is said to be reversible if \(ab=0\) implies \(ba=0\) for all \(a,b\in R\). The main problem of this paper is the question when the group ring \(K[G]\) of a group \(G\) over a field \(K\) is reversible. The authors prove that if \(G\) is a non-Abelian torsion group and \(K[G]\) is reversible, then \(G\) is ...

A STUDY ON TRI REVERSIBLE RINGS [PDF]

open access: yesJournal of Algebraic Systems
This article embodies a ring theoretic property which, preserves the reversibility of elements at non-zero tripotents. A ring R is defined as quasi tri reversible if any non-zero tripotent element ab of R implies ba is also a tripotent element in R for a,

Conformation-driven reversibility control in ring-opening metathesis polymerization of non-bicyclic cyclooctenes [PDF]

open access: yesNature Communications
Reversible ring-opening metathesis polymerization (ROMP) of cyclooctene (COE) derivatives remains a challenge due to their high ring strain energies (RSEs).

On Double Cyclic Codes over Finite Chain Rings for DNA Computing [PDF]

open access: yesEntropy
Let e be a fixed positive integer and n1,n2 be odd positive integers. The main objective of this article is to investigate the algebraic structure of double cyclic codes of length (n1,n2) over the finite chain ring Re = F4e+vF4e, where v2=0.

On Axis-Reversible Rings

open access: yesMathematics
This work explores the notion of axis-reversible rings, a generalization of axis-commutative rings. The objective is to investigate their characteristics and relevance within the wider context of ring theory.

ON STRONGLY REVERSIBLE RINGS

open access: yesTaiwanese Journal of Mathematics, 2008
A ring $R$ is called strongly reversible, if whenever polynomials $f(x),$ $g(x)$ in $R[x]$ satisfy $f(x)g(x)=0$, then $g(x)f(x)=0$. It is proved that a ring $R$ is strongly reversible if and only if its polynomial ring $R[x]$ is strongly reversible if and only if its Laurent polynomial ring $R[x,x^{-1}]$ is strongly reversible.

On Reversible Group Rings [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2006
Let G be an arbitrary finite group, R be a finite associative ring with identity and RG be the group ring. We show that ℤ2Q8 is the minimal reversible group ring which is not symmetric, and we also characterise the finite rings R for which RQ8 is reversible. The first result extends a result of Gutan and Kisielewicz which shows that ℤ2Q8 is the minimal
