On the Quotients of Regular Operators
We give some results about quotients of regular operators on Banach lattices by the linear span of the positive M-weakly and positive L-weakly compact operators.

Weighted Composition Operators Between Extended Lipschitz Algebras on Compact Metric Spaces [PDF]
In this paper, we provide a complete description of weighted composition operators between extended Lipschitz algebras on compact metric spaces. We give necessary and sufficient conditions for the injectivity and the sujectivity of these operators.

Properties of Fuzzy Compact Linear Operators on Fuzzy Normed Spaces
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 ...

On Power Compact Operators [PDF]
We give an operator theoretic proof of the following result of D. G. Tacon: Theorem. If { T n } \{ {T_n}\} is a sequence of bounded linear operators in a complex infinite dimensional Hilbert space with the property that for every bounded sequence {

Analytic Families of Self-Adjoint Compact Operators Which Commute with Their Derivative
Spectral properties of analytic families of compact operators on a Hilbert space are studied. The results obtained are then used to establish that an analytic family of self-adjoint compact operators on a Hilbert space $\mathcal{H},$ which commute with ...

Some properties of weak Banach-Saks operators [PDF]
We establish necessary and sufficient conditions under which weak Banach-Saks operators are weakly compact (respectively, {\rm L}-weakly compact; respectively, {\rm M}-weakly compact).

A property of compact operators [PDF]
The present paper is inspired by the work of \textit{V. F. Babenko} and \textit{S. A. Pichugov} [Ukr. Mat. Zh. 33, 491-492 (1981; Zbl 0492.47018)] and that of \textit{I. K. Daugavet} [Usp. Mat. Nauk. 18, No.5(113), 157-158 (1963; Zbl 0138.386)]. They proved that if T is any compact linear operator on either of the Banach spaces \(L^ 1(0,1)\) or C[0,1],

Continuous linear operators on Orlicz-Bochner spaces
Let (Ω, Σ, μ) be a complete σ-finite measure space, φ a Young function and X and Y be Banach spaces. Let Lφ(X) denote the corresponding Orlicz-Bochner space and Tφ∧$\begin{array}{} \displaystyle \mathcal T^\wedge_\varphi \end{array}$ denote the finest ...

On the Lattice Properties of Almost L-Weakly and Almost M-Weakly Compact Operators
We establish the domination property and some lattice approximation properties for almost L-weakly and almost M-weakly compact operators. Then, we consider the linear span of positive almost L-weakly (resp., almost M-weakly) compact operators and give ...

The Bidual of the Compact Operators [PDF]
For a Banach space X, let \(X^*\) be the dual, B(X) the Banach algebra of bounded linear operators, and \(B_ F(X)\), \(B_ K(X)\) and \(B_ I(K)\) the ideals of finite rank, compact, and integrable operators, respectivly. \textit{A. Grothendieck} [Mem. Am. Math. Soc. 16, 140 p.
