Feebly r-clean ideal and feebly *-r-clean ideal

open access: yesRatio Mathematica, 2023
In this article, we introduce the concept of feebly r-clean ring and feebly ∗-r-clean ring. A ring R is defined to be feebly r-clean, if every element a can be written as a = r + e − f, where u is a regular and e, f are orthogonal idempotents and A ...

Symmetrization in Clean and Nil-Clean Rings [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
We introduce and investigate D-clean and D-nil-clean rings as well as some other closely related symmetric versions of cleanness and nil-cleanness. A comprehensive structural characterization is given for these symmetrically clean and symmetrically nil ...

Medium nil *-clean rings

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2022
A *-ring R is called a medium *-clean ring if every element in R is the sum or difference of a nilpotent with a projection that commute. Fundamenta properties of such *-rings are obtained.

On quotient clean hyperring [PDF]

open access: yesJournal of Hyperstructures, 2015
In this paper, we introduce the notion of quotient Krasner hyperrings and prove that if I is a normal ideal of Krasner hyperring (R, +, ·), then quotient clean Krasner hyperring considered in [1] by Talebi et. al are just clean rings.

Left-Right Cleanness and Nil Cleanness in Unital Rings

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
We introduce the notions of left and right cleanness and nil cleanness in rings showing their close relationships with the classical concepts of cleanness and nil cleanness.

Graphene Rings in Magnetic Fields: Aharonov-Bohm Effect and Valley Splitting [PDF]

open access: yes, 2009
We study the conductance of mesoscopic graphene rings in the presence of a perpendicular magnetic field by means of numerical calculations based on a tight-binding model.

On γ-Clean Rings

open access: yesScience Journal of University of Zakho, 2017
In this paper we introduce the concept of -clean ring and we discuss some relations between - clean ring and other rings with explaining by some examples. Also, we give some basic properties of it.

The strong nil-cleanness of semigroup rings

open access: yesOpen Mathematics, 2020
In this paper, we study the strong nil-cleanness of certain classes of semigroup rings. For a completely 0-simple semigroup M=ℳ0(G;I,Λ;P)M={ {\mathcal M} }^{0}(G;I,\text{Λ};P), we show that the contracted semigroup ring R0[M]{R}_{0}{[}M] is ...

The relationships between clean rings, r-clean rings, and f-clean rings [PDF]

open access: yesAIP Conference Proceedings, 2018
Suppose R is a ring with identity. R called a regular ring if each element is a regular element. A ring R is called an r-clean ring if every element in R can be expressed as the sum of a regular element and an idempotent element. An element in the ring R is called clean if it can be expressed as the sum of a unit element and an idempotent element, so ...

Strongly Invo. T- Clean Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics
In this paper, we present the idea of a strongly invo. T-clean rings, which we define as rings with every a in R having the formula a = t + v, where t is a tripotent and v is an order two unit that commute.
