On Composition Operators on A2 [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 1995 If (?) is an analytic function mapping the open unit disk D into itself and A2 is the Bergman space of analytic functions on D, the compositon operator C?, on A2 is defined by C?f=fo?feA2.

M-quasi-hyponormal composition operators [PDF]
International Journal of Mathematics and Mathematical Sciences, 1987 A necessary and sufficient condition is obtained for M-quasi-hyponormal composition operators. It has also been proved that the class of M-quasi-hyponormal composition operators coincides with the class of M-paranormal composition operators. Existence of

Composition operators from harmonic $ \mathcal{H}^{\infty} $ space into harmonic Zygmund space
AIMS Mathematics, 2023 This research paper sought to characterize the boundedness and compactness of composition operators from the space $ \mathcal{H}^{\infty} $ of bounded harmonic mappings into harmonic Zygmund space $ \mathcal{Z}_H $, on the open unit disk. Furthermore, we

On Composition Operators on N+(?) [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 1998 Let N(?) denote the class of analytic functions fin a domain ?, contained in the complex numbers C, such that log(1+| f |) has a harmonic majorant. The subclass N+(?) of N(?) consists of all f such that log(1+| f |) has a quasi-bounded harmonic majorant.

Concrete Operators, 2022 Let (X, 𝒜, μ) be a σ−finite measure space. A transformation ϕ : X → X is non-singular if μ ∘ ϕ−1 is absolutely continuous with respect with μ. For this non-singular transformation, the composition operator Cϕ: 𝒟(Cϕ) → L2(μ) is defined by Cϕf = f ∘ ϕ, f ∈

D-metric Spaces and Composition Operators Between Hyperbolic Weighted Family of Function Spaces
Cubo, 2020 The aim of this paper is to introduce new hyperbolic classes of functions, which will be called ${\mathcal{B}}^{*} _{\alpha,\;\log}$ and ${ F ^{*}_{\log}}(p,q,s)$ classes.

Hilbert-Schmidtness of weighted composition operators and their differences on Hardy spaces [PDF]
Opuscula Mathematica, 2020 Let \(u\) and \(\varphi\) be two analytic functions on the unit disk \(\mathbb{D}\) such that \(\varphi(\mathbb{D}) \subset \mathbb{D}\). A weighted composition operator \(uC_{\varphi}\) induced by \(u\) and \(\varphi\) is defined on \(H^2\), the Hardy ...

Binormal and complex symmetric weighted composition operators on the Fock Space over $\mathbb{C}$
Математичні Студії, 2023 In this paper, we give simple characterization of binormal weighted composition operators $C_{\psi, \phi}$ on the Fock space over $\mathbb{C}$ where weight function is of the form $\psi(\zeta) = e^{\langle \zeta, c \rangle}$ for some $c \in \mathbb{C ...

Weighted composition operators on Hardy–Smirnov spaces
Concrete Operators, 2022 Operators of type f → ψf ◦ φ acting on function spaces are called weighted composition operators. If the weight function ψ is the constant function 1, then they are called composition operators.
