Regular multilinear operators on C(K) spaces [PDF]

open access: yes, 1999
The purpose of this paper is to characterise the class of regular continuous multilinear operators on a product of C(K) spaces, with values in an arbitrary Banach space.

Orthogonally Biadditive Operators

open access: yesJournal of Function Spaces, 2021
In this article, we introduce and study a new class of operators defined on a Cartesian product of ideal spaces of measurable functions. We use the general approach of the theory of vector lattices.

Nijenhuis geometry III: gl-regular Nijenhuis operators [PDF]

open access: yes, 2023
We study Nijenhuis operators, that is, (1,1)-tensors with vanishing Nijenhuis torsion under the additional assumption that they are gl-regular, i.e., every eigenvalue has geometric multiplicity one.

A note on the relationship between three classes of operators on Riesz spaces

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2019
Following several papers in the prior literature, we study the relationship between order bounded operators, topologically bounded operators and topologically continuous operators.

Nijnehuis Geometry III: gl-regular Nijenhuis operators [PDF]

open access: yes, 2020
We study Nijenhuis operators, that is, (1,1)-tensors with vanishing Nijenhuis torsion under the additional assumption that they are gl-regular, i.e., every eigenvalue has geometric multiplicity one.

Control Room Operators’ Cue Utilization Predicts Cognitive Resource Consumption During Regular Operational Tasks

open access: yesFrontiers in Psychology, 2019
This study was designed to examine whether qualified practitioners’ cue utilization is predictive of their sustained attention performance during regular operational tasks.

Weakly hereditary regular closure operators [PDF]

open access: yes, 1993
We present characterizations of subcategories inducing weakly hereditary regular closure operators. These characterizations are applicable, in particular, to the category Top of topological spaces and continuous maps and to Abelian categories.

A Study of Complex Dombi Fuzzy Graph With Application in Decision Making Problems

open access: yesIEEE Access, 2022
A complex fuzzy set (CFS) is a generalization of a fuzzy set (FS) in which a limit of degrees occurs on the complex plane with unit disc. The averaging operators are a key part of turning all the data into one value.

LOCAL SPECTRAL PROPERTY OF RELATIVELY REGULAR OPERATORS [PDF]

open access: yes, 2017
In this paper, we study some relatively regular operators T such that T = TST for some S is an element of L(H). We give some spectral and local spectral properties between T and S.
