Antinormal Weighted Composition Operators [PDF]
Abstract and Applied Analysis, 2016 Let l2=L2N,μ, where N is set of all positive integers and μ is the counting measure whose σ-algebra is the power set of N. In this paper, we obtain necessary and sufficient conditions for a weighted composition operator to be antinormal on the Hilbert ...

Supercyclicity and Resolvent Condition for Weighted Composition Operators [PDF]
Computational Methods and Function Theory, 2021 For pairs of holomorphic maps $$(u,\psi )$$ ( u , ψ ) on the complex plane, we study some dynamical properties of the weighted composition operator $$W_{(u,\psi )}$$ W ( u , ψ ) on the Fock spaces.

Weighted Composition Operators on the Zygmund Space [PDF]
Abstract and Applied Analysis, 2012 We characterize the boundedness and compactness of the weighted composition operator on the Zygmund space Z={f∈H(D):supz∈D(1-|z|2)|f″(z)|

Weighted Composition Operators on Hardy Spaces
Journal of Mathematical Analysis and Applications, 2001 AbstractLet ϕ, ψ be analytic functions defined on D, such that ϕ(D)⊆D. The operator given by f↦ψ(f∘ϕ) is called a weighted composition operator. In this paper we deal with the boundedness, compactness, weak compactness, and complete continuity of weighted composition operators on Hardy spaces Hp (1 ...

Invertible and Isometric Weighted Composition Operators
Mediterranean Journal of Mathematics, 2022 AbstractWe consider abstract Banach spaces of analytic functions on general bounded domains that satisfy only a minimum number of axioms. We describe all invertible (equivalently, surjective) weighted composition operators acting on such spaces. For the spaces of analytic functions in the disk whose norm is given in terms of a natural seminorm (such ...

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 ,

Approximation numbers of weighted composition operators [PDF]
Journal of Functional Analysis, 2018 We study the approximation numbers of weighted composition operators $f\mapsto w\cdot(f\circ )$ on the Hardy space $H^2$ on the unit disc. For general classes of such operators, upper and lower bounds on their approximation numbers are derived. For the special class of weighted lens map composition operators with specific weights, we show how much the

Weighted Composition Operators and Supercyclicity Criterion [PDF]
International Journal of Mathematics and Mathematical Sciences, 2011 We consider an equivalent condition to the property of Supercyclicity Criterion, and then we investigate this property for the adjoint of weighted composition operators acting on Hilbert spaces of analytic functions.
