ON THE HYPERBOLIC WEIGHTED COMPOSITION OPERATORS [PDF]

International Journal of Pure and Apllied Mathematics, 2016
In this present paper, we investigate the hypercyclicity of a hyperbolic weighted composition operator acting on some Banach spaces of holomorphic functions on the open unit ball in C N.

Toeplitz-Superposition Operators on Analytic Bloch Spaces

Journal of Function Spaces, 2021
The important purpose of this current work is to study a new class of operators, the so-called Toeplitz-superposition operators as an expansion of the weighted known composition operators, induced by such continuous entire functions mapping on bounded ...

Composition Operators on Weighted Modulation Spaces

Mediterranean Journal of Mathematics
Abstract We study composition operators whose symbols are suitable perturbations of the identity and which act between different weighted modulation classes. We consider both modulation spaces formed by tempered distributions and those whose elements are ultradistributions defined in terms of a subadditive weight.

Weighted modular inequalities for monotone functions

Journal of Inequalities and Applications, 1997
Weight characterizations of weighted modular inequalities for operators on the cone of monotone functions are given in terms of composition operators on arbitrary non-negative functions with changes in weights. The results extend to modular inequalities,

Normaloid weighted composition operators on H2 [PDF]

Journal of Mathematical Analysis and Applications, 2018
When \ph\ is an analytic self-map of the unit disk with Denjoy-Wolff point $a \in \D$, and $ρ(\W) = ψ(a)$, we give an exact characterization for when \W\ is normaloid. We also determine the spectral radius, essential spectral radius, and essential norm for a class of non-compact composition operators whose symbols have Denjoy-Wolff point in \D.

The compactness of the sum of weighted composition operators on the ball algebra

Journal of Inequalities and Applications, 2011
In this paper, we investigate the compactness of the sum of weighted composition operators on the unit ball algebra, and give the characterization of compact differences of two weighted composition operators on the ball algebra.
