Weakly Compact Composition Operators on VMO

open access: yesRocky Mountain Journal of Mathematics, 2002
The paper gives several necesssary and/or sufficient conditions for an analytic composition operator \(C_\varphi\) to be weakly compact on VMOA of the unit disk.

Topological structure of solution sets for fractional evolution inclusions of Sobolev type

open access: yesBoundary Value Problems, 2018
The paper is devoted to establishing the solvability and topological property of solution sets for the fractional evolution inclusions of Sobolev type. We obtain the existence of mild solutions under the weaker conditions that the semigroup generated by −

Weakly compact groups of operators [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
It is shown that the weakly closed algebra generated by a weakly compact group of operators on a Banach space is reflexive and equals its second commutant. Also, an example is given to show that the generator of a monothetic weakly compact group of operators need not have a logarithm in the algebra of all bounded linear operators on the underlying ...

Some Classes of Continuous Operators on Spaces of Bounded Vector-Valued Continuous Functions with the Strict Topology

open access: yesJournal of Function Spaces, 2015
Let X be a completely regular Hausdorff space and let E,·E and (F,·F) be Banach spaces. Let Cb(X,E) be the space of all E-valued bounded, continuous functions on X, equipped with the strict topology βσ. We study the relationship between important classes

On weakly compact operators

open access: yesMathematische Annalen, 1992
For a finite, complete and positive measure space \((\Omega,\Sigma,\mu)\) and Banach spaces \(X\) and \(Y\) over the real or complex field, mappings \(U\) from \(\Omega\) into \(W(X,Y)\), the space of weakly compact operators from \(X\) to \(Y\), are considered.

The Set of Idempotents in the Weakly Almost Periodic Compactification of the Integers is not Closed [PDF]

open access: yes, 2000
This paper answers negatively the question of whether the sets of idempotents in the weakly almost periodic compacti?cations of (N; +) and (Z; +) are ...

Factoring compact and weakly compact operators through reflexive Banach lattices

open access: yes, 1984
When does a weakly compact operator between two Banach spaces factor through a reflexive Banach lattice? This paper provides some answers to this question. One of the main results: If an operator between two Banach spaces factors through a Banach lattice

The (𝐷) Property in Banach Spaces

open access: yesAbstract and Applied Analysis, 2012
A Banach space 𝐸 is said to have (D) property if every bounded linear operator 𝑇∶𝐹→𝐸∗ is weakly compact for every Banach space 𝐹 whose dual does not contain an isomorphic copy of 𝑙∞.

A Riesz representation theory for completely regular Hausdorff spaces and its applications

open access: yesOpen Mathematics, 2016
Let X be a completely regular Hausdorff space, E and F be Banach spaces. Let Cb(X, E) be the space of all E-valued bounded, continuous functions on X, equipped with the strict topology β.
