(λ, μ)‐Fuzzy Version of Ideals, Interior Ideals, Quasi‐Ideals, and Bi‐Ideals [PDF]

open access: yesJournal of Applied Mathematics, 2012
We introduced (λ, μ)‐fuzzy ideals, (λ, μ)‐fuzzy interior ideals, (λ, μ)‐fuzzy quasi‐ideals, and (λ, μ)‐fuzzy bi‐ideals of an ordered semigroup and studied them. When λ = 0 and μ = 1, we meet the ordinary fuzzy ones. This paper can be seen as a generalization of Kehayopulu and Tsingelis (2006), Kehayopulu and Tsingelis (2007), and Yao (2009).

Generators of maximal left ideals in Banach algebras [PDF]

open access: yes, 2012
In 1971, Grauert and Remmert proved that a commutative, complex, Noetherian Banach algebra is necessarily finite-dimensional. More precisely, they proved that a commutative, complex Banach algebra has finite dimension over C whenever all the closed ...

Maximal ideals in the algebra of operators on certain Banach spaces. [PDF]

open access: yes, 2002
For a Banach space $\mathfrak{X}$, let $\mathcal{B}(\mathfrak{X})$ denote the Banach algebra of all continuous linear operators on $\mathfrak{X}$. First, we study the lattice of closed ideals in $\mathcal{B}(\mathfrak{J}_p)$, where $1 < p < \infty$ and $\

2-convexity and 2-concavity in Schatten ideals. [PDF]

open access: yes, 1996
The properties p-convexity and q-concavity are fundamental in the study of Banach sequence spaces (see [L-TzII]), and in recent years have been shown to be of great significance in the theory of the corresponding Schatten ideals ([G-TJ], [LP-P] and many ...

THE IDEALS OF AN IDEAL EXTENSION [PDF]

open access: yesJournal of Algebra and Its Applications, 2010
Given two unital associative rings R ⊆ S, the ring S is said to be an ideal (or Dorroh) extension of R if S = R ⊕ I, for some ideal I ⊆ S. In this note, we investigate the ideal structure of an arbitrary ideal extension of an arbitrary ring R. In particular, we describe the Jacobson and upper nil radicals of such a ring, in terms of the Jacobson and ...

Smarandache fantastic ideals of Smarandache BCI-algebras [PDF]

open access: yes, 2006
The notion of Smarandache fantastic ideals is introduced, examples are given, and related properties are investigated. Relations among Q-Smarandache fresh ideals, Q-Smarandache clean ideals and Q-Smarandache fantastic ideals are given. A characterization

A Characterization of Semiprime Rings with Homoderivations

open access: yesJournal of New Theory, 2023
This paper is focused on the commutativity of the laws of semiprime rings, which satisfy some algebraic identities involving homoderivations on ideals. It provides new and notable results that will interest researchers in this field, such as “R contains ...
