Spectrum perturbations of compact operators in a Banach space

Open Mathematics, 2019
For an integer p ≥ 1, let Γp be an approximative quasi-normed ideal of compact operators in a Banach space with a quasi-norm NΓp(.) and the ...

Remark on quasi-ideals of ordered semigroups [PDF]

Pure Mathematics and Applications, 2015
Abstract The aim is to correct part of the Remark 3 of my paper “On regular, intra-regular ordered semigroups” in Pure Math. Appl. (PU.M.A.) 4, no. 4 (1993), 447-461. On this occasion, some further results and the similarity between the po-semigroups and the le-semigroups are discussed.

Characterizations of Regular Ordered Semirings by Ordered Quasi-Ideals

International Journal of Mathematics and Mathematical Sciences, 2016
We introduce the notion of an ordered quasi-ideal of an ordered semiring and show that ordered quasi-ideals and ordered bi-ideals coincide in regular ordered semirings.

Generalized Fuzzy Quasi-Ideals in Ordered Semigroups

International Journal of Algebra and Statistics, 2012
In this paper, we introduce the concept of an (; )-fuzzy quasiideal in ordered semigroups, which is a generalization of fuzzy quasi-ideals in ordered semigroups. By using this concept, we de ne semiprime (2; 2 _q)-fuzzy quasi-ideals and some basic results of an ordered semigroup are discussed.

On quasi-ideals and bi-ideals in ternary semirings

International Journal of Mathematics and Mathematical Sciences, 2005
We introduce the notions of quasi-ideal and bi-ideal in ternary semirings and study some properties of these two ideals. We also characterize regular ternary semiring in terms of these two subsystems of ternary semirings.

Soft Union Bi-quasi Ideals of Semigroup

International Journal of Analysis and Applications
Mathematicians attach importance to extending ideals in algebraic structures. The concept of bi-quasi (ƁԚ) ideal was introduced as a generalization version of quasi-ideal, bi-ideal, and left (right) ideals in semigroups. This paper applies this concept to soft set theory and semigroups, introducing the notion of "Soft union (S-uni) ƁԚ ideal." The aim ...

Ideal-Based Quasi Cozero Divisor Graph of a Commutative Ring

Journal of Mathematics
Let R be a commutative ring with identity and I be an ideal of R. The zero-divisor graph of R with respect to I, denoted by ΓIR, is the graph whose vertices are the set x∈R∖I xy∈I for some y∈R∖I with distinct vertices x and y are adjacent if and only if ...

Soft Intersection Bi-quasi Ideals of Semigroup

Türk Doğa ve Fen Dergisi
Mathematicians find it valuable to extend the concept of ideals within algebraic structures. The bi-quasi (ƁԚ) ideal was introduced as a broader version of quasi-ideal, bi-ideal, and left (right) ideals in semigroups. This paper applies this concept to soft set theory and semigroups, introducing the "Soft intersection (S-int) ƁԚ ideal." The goal is to ...

Soft Intersection Bi-interior Ideals of Semigroups

Journal of Innovative Science and Engineering
Generalizing the ideals of an algebraic structure has shown to be both beneficial and interesting for mathematicians. In this context, the idea of the bi-interior ideal was introduced as a generalization of the bi-ideal and interior ideal of a semigroup.
