The Eigenfunctions of a Certain Composition Operator [PDF]
, 1998 The composition operator on the classical Hardy space H2, induced by a hyperbolic disk automorphism is considered. It is investigated when a H2-function induces under the given operator a minimal invariant cyclic subspace.

Isometric multiplication operators and weighted composition operators of BMOA
Journal of Inequalities and Applications, 2021 Let u be an analytic function in the unit disk D $\mathbb{D}$ and φ be an analytic self-map of D $\mathbb{D}$ . We give characterizations of the symbols u and φ for which the multiplication operator M u $M_{u}$ and the weighted composition operator M u ,

On Invertible Weighted Composition Operator on Hardy Space H^2 [PDF]
, 2016 In this paper we study the product of a weighted composition operator , with the adjoint of a weighted composition operator , ∗ on the Hardy space ℍ2 . The order of the product give rise to different cases .

Composition Operators Belonging to Operator Ideals
Journal of Mathematical Analysis and Applications, 1999 Let \(D\) be the unit disc \(\{z\in\mathbb{C}:|z|< 1\}\) of the complex plane \(\mathbb{C}\), and let \(\mu\) be the normalized Lebesgue measure on \(D\).

An integral operator on the classes \(\mathcal{S}^{\ast}(\alpha )\) and \(\mathcal{CVH}(\beta )\) [PDF]
, 2013 The purpose of this paper is to study some properties related to convexity order and coefficients estimation for a general integral operator. We find the convexity order for this operator, using the analytic functions from the class of starlike functions

Composition and multiplication operators between Orlicz function spaces
Journal of Inequalities and Applications, 2016 Composition operators and multiplication operators between two Orlicz function spaces are investigated. First, necessary and sufficient conditions for their continuity are presented in several forms.

Antinormal Weighted Composition Operators [PDF]
Abstract and Applied Analysis, 2016 Letl2=L2N,μ, whereNis set of all positive integers andμis the counting measure whoseσ-algebra is the power set ofN. In this paper, we obtain necessary and sufficient conditions for a weighted composition operator to be antinormal on the Hilbert spacel2. We also determine a class of antinormal weighted composition operators on Hardy spaceH2D.

Recurrence of Composition Operators on Discrete Banach Spaces
AxiomsLet (T,d) be an unbounded and locally finite metric space that contains a distinguished element o. Let L∞(T) denote the discrete Banach space and L0(T) its subspace of functions vanishing at infinity.

A new class of composition operators
International Journal of Mathematics and Mathematical Sciences, 1987 A new class of composition operators Pϕ:H2(T)→H2(T), with ϕ:T→D¯ is introduced. Sufficient conditions on ϕ for Pϕ to be bounded and Hilbert-Schmidt are obtained.
