A class of operator related weighted composition operators between Zygmund space [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
Let $\mathbb {D}$ be the open unit disk in the complex plane $\mathbb{C}$ and $H(\mathbb{D})$ be the set of all analytic functions on $\mathbb{D}$. Let $u, v\in H(\mathbb{D})$ and $\varphi$ be an analytic self-map of $\mathbb{D}$.

The essential spectrum, norm, and spectral radius of abstract multiplication operators

open access: yesConcrete Operators, 2023
Let EE be a complex Banach lattice and TT is an operator in the center Z(E)={T:∣T∣≤λIfor someλ}Z\left(E)=\left\{T:| T| \le \lambda I\hspace{0.33em}\hspace{0.1em}\text{for some}\hspace{0.1em}\hspace{0.33em}\lambda \right\} of EE. Then, the essential norm ‖

Essential Norm of the Weighted Composition Operators Between Growth Space [PDF]

open access: yesSahand Communications in Mathematical Analysis
For $\alpha>0$, the growth space $\mathcal{A}^{-\alpha}$ is the space of all function $f\in H(\DD)$ such that $$\left\|f\right\|_{\mathcal{A}^{-\alpha}}=\sup_{z\in\DD}\left(1-\left|z\right|^2\right)^\alpha \left|f(z)\right|

Norms of a Product of Integral and Composition Operators between Some Bloch-Type Spaces

open access: yesAxioms, 2023
We present some formulas for the norm, as well as the essential norm, of a product of composition and an integral operator between some Bloch-type spaces of analytic functions on the unit ball, in terms of given symbols and weights.

Should I believe the truth? [PDF]

open access: yes, 2010
Many philosophers hold that a general norm of truth governs the attitude of believing. In a recent and influential discussion, Krister Bykvist and Anandi Hattiangadi raise a number of serious objections to this view. In this paper, I concede that Bykvist

Uniform local amenability [PDF]

open access: yes, 2013
The main results of this paper show that various coarse (‘large scale’) geometric properties are closely related. In particular, we show that prop- erty A implies the operator norm localisation property, and thus that norms of operators associated to a ...
