Fuzzy Operator Ideals

open access: yesJournal of Applied Science and Engineering, 2022
Although the systematic emergence of the fuzzy functional analysis theory has started in the last few years, we are starting to construct a new theory of fuzzy operator ideals inspired by the classical (crisp) operator ideals theory.

Small operator ideals formed by s numbers on generalized Cesáro and Orlicz sequence spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2018
In this article, we establish sufficient conditions on the generalized Cesáro and Orlicz sequence spaces E $\mathbb{E}$ such that the class SE $S_{\mathbb{E}}$ of all bounded linear operators between arbitrary Banach spaces with its sequence of s-numbers

Monomial Ideals under Ideal Operations [PDF]

open access: yesCommunications in Algebra, 2015
In this paper, we show for a monomial ideal $I$ of $K[x_1,x_2,\ldots,x_n]$ that the integral closure $\ol{I}$ is a monomial ideal of Borel type (Borel-fixed, strongly stable, lexsegment, or universal lexsegment respectively), if $I$ has the same property.

Representing the Banach operator ideal of completely continuous operators; pp. 189–193 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2017
Let V ;W∞ and W be the operator ideals of completely continuous, weakly ∞-compact, and weakly compact operators, respectively. In a recent paper, William B. Johnson, Eve Oja, and the author proved that V = W∞ ◦W -1 (Johnson, W. B., Lillemets, R.,

Operator Ideals and Operator Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
We prove that every full symmetrically normed ideal of operators on a Hilbert space is realizable as the set of completely bounded maps between two homogeneous operator Hilbert spaces, with the c.b. norm equivalent to (but in general not equal to) the symmetric norm. We show that one can have equality of the c.b.

Novel Neutrosophic Objects Within Neutrosophic Topology [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This essay intends to introduce and study many new neutrosophic objects within neutrosophic topologies, such as the neutrosophic point, the neutrosophic quasi-concomitant, the neutrosophic quasi neighborhood, the neutrosophic ideals, the neutrosophic ...

On quasi-prime differential semiring ideals

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020
The notion of a \verb"quasi-prime ideal", for the first time, was introduced in differential commutative rings, i.e. commutative rings considered together with a derivation, as differential ideals maximal among those not meeting some multiplicatively ...

Lattice of weak hyper K-ideals of a hyper K-algebra [PDF]

open access: yesJournal of Algebraic Systems, 2014
In this note, we study the lattice structure on the class of all weak hyper K-ideals of a hyper K-algebra. We first introduce the notion of (left,right) scalar in a hyper K-algebra which help us to characterize the weak hyper K-ideals generated by a ...

An η-Intuitionistic Fuzzy Rings Structure

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2023
In this article, we present the structure of η-intuitionistic fuzzy ring. An η-intuitionistic fuzzy ring is a structure which is built with combinating the definition of fuzzy ring, intuitionistic fuzzy set, and η-intuitionistic fuzzy set.

IDEAL OPERATORS AND HIGHER INDESCRIBABILITY

open access: yesThe Journal of Symbolic Logic, 2022
AbstractWe investigate properties of the ineffability and the Ramsey operator, and a common generalization of those that was introduced by the second author, with respect to higher indescribability, as introduced by the first author. This extends earlier investigations on the ineffability operator by James Baumgartner, and on the Ramsey operator by Qi ...
