Some Topological Character of Neutrosophic normed spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
The concept of neutrosophic normed spaces was introduced by Murat Kirisci* and Necip Simsek [3]. In this paper, by using the compact operator ψ(zj ) and the concept of statistical convergence.

On the class of $\text{b}$-L-weakly and order M-weakly compact operators [PDF]

open access: yesMathematica Bohemica, 2020
In this paper, we introduce and study new concepts of b-L-weakly and order M-weakly compact operators. As consequences, we obtain some characterizations of KB-spaces.

On linear sections of orthogonally additive operators

open access: yesМатематичні Студії, 2022
Our first result asserts that, for linear regular operators acting from a Riesz space with the principal projection property to a Banach lattice with an order continuous norm, the $C$-compactness is equivalent to the $AM$-compactness. Next we prove that,

ON REPRESENTATION OF ONE CLASS OF SCHMIDT OPERATORS

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
In this paper, unitary symmetrizers are considered. It is well known that using Newton operatoralgorithm, similar to the usual Newton algorithm, for extracting the square root, one can provethat for every Hermitian operator T 0, there exists a unique ...

Some characterizations of surjective operators on banach lattices [PDF]

open access: yesJournal of Hyperstructures, 2018
The concepts of compact and weakly compact operators on Banach spaces are considered and investigated in several papers. In this paper, taking idea from this notations, we consider the concept surjective compact and weakly compact operators on Banach ...

Properties of Fuzzy Compact Linear Operators on Fuzzy Normed Spaces

open access: yesمجلة بغداد للعلوم, 2019
In this paper the definition of fuzzy normed space is recalled and its basic properties. Then the definition of fuzzy compact operator from fuzzy normed space into another fuzzy normed space is introduced after that the proof of an operator is fuzzy ...

Composition operator induced by ?(z) = sz + t for which |s|?1, |t|<1 and |s|+|t|?1

open access: yesمجلة بغداد للعلوم, 2010
We study in this paper the composition operator that is induced by ?(z) = sz + t. We give a characterization of the adjoint of composiotion operators generated by self-maps of the unit ball of form ?(z) = sz + t for which |s|?1, |t|

Extension of Compact Operators from DF-spaces to C(K) spaces

open access: yesApplied General Topology, 2006
It is proved that every compact operator from a DF-space, closed subspace of another DF-space, into the space C(K) of continuous functions on a compact Hausdorff space K can be extended to a compact operator of the total DF-space.

About Riesz theory of compact operators

open access: yesBibechana, 2012
In this paper, it is shown that every compact operators are bounded and continuous. The bounded and continuous properties of an operator is sufficient for a Riesz operator.
