Sums of Weighted Differentiation Composition Operators [PDF]

open access: yesComplex Analysis and Operator Theory, 2019
We solve an interpolation problem in $A^p_ $ involving specifying a set of (possibly not distinct) $n$ points, where the $k^{\textrm{th}}$ derivative at the $k^{\textrm{th}}$ point is up to a constant as large as possible for functions of unit norm. The solution obtained has norm bounded by a constant independent of the points chosen.

Weighted Composition Operators on Some Weighted Spaces in the Unit Ball

open access: yesAbstract and Applied Analysis, 2008
Let Bn be the unit ball of Cn, H(Bn) the space of all holomorphic functions in Bn. Let u∈H(Bn) and α be a holomorphic self-map of Bn. For f∈H(Bn), the weigthed composition operator uCα is defined by (uCαf)(z)=u(z)f(α(z)),z∈Bn.

Weighted Composition Operators and Supercyclicity Criterion [PDF]

open access: yesInternational 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.

A Review on Classes of Composition Operators

open access: yesپژوهش‌های ریاضی, 2020
Introduction In 1976, A. Lambert characterized subnormal weighted shifts. Then he studied hyponormal weighted composition operators on  in 1986 and in 1988 subnormal composition operators studied again by him. Recently, A. Lambert, et al., have published

Binormal and complex symmetric weighted composition operators on the Fock Space over $\mathbb{C}$

open access: yesМатематичні 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 ...
