Numerical Ranges of Normal Weighted Composition Operators on the Fock Space of CN

Journal of Function Spaces, 2018
Numerical ranges of normal weighted composition operators on the Fock space of CN are completely characterized. The main result shows that numerical ranges of such operators are closely related to their composition symbols.

Weighted Composition Operators on BMOA [PDF]

Computational Methods and Function Theory, 2008
The author completely characterizes the boundedness and compactness of the weighted composition operator \(W_{\psi,\varphi}f=\psi (f\circ \varphi)\) acting on \(BMOA\) and \(VMOA\) of the unit disc. The results extend and unify those known for the cases \(\varphi(z)=z\) and \(\psi(z)=1\) corresponding to the multiplication operator \(M_\psi\) [see ...

Binormal Weighted Composition Operators on the Fock Space

Journal of Function Spaces
The aim of this paper is to obtain the sufficient and necessary conditions for weighted composition operators uCφ with φz=az+b a≤1, uz=ced¯z, where a,b,c,d∈ℂ, to be binormal or quasinormal on the Fock space F2. Surprisingly, the normality, quasinormality,

Weighted Differentiation Composition Operators to Bloch-Type Spaces

Abstract and Applied Analysis, 2013
We characterized the boundedness and compactness of weighted differentiation composition operators from BMOA and the Bloch space to Bloch-type spaces. Moreover, we obtain new characterizations of boundedness and compactness of weighted differentiation ...

Fixed point results on nonlinear composition operators A ∘ B $A\circ B$ and applications

Journal of Inequalities and Applications
This paper investigates a class of composition operators: the nonlinear operator T = A ∘ B $T=A\circ B$ and the sum-type operator T = A ∘ B + C $T=A\circ B+C$ , where A, B, and C are either single or bivariate operators. Here, “∘” denotes the composition
