Weighted Composition Operators from Hardy to Zygmund Type Spaces

open access: yesAbstract and Applied Analysis, 2013
This paper aims at studying the boundedness and compactness of weighted composition operator between spaces of analytic functions. We characterize boundedness and compactness of the weighted composition operator from the Hardy spaces to the Zygmund ...

Weighted differentiation composition operators on the $Q_K(p,q)$ spaces and‎ their essential ‎norms‎ [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, firstly we obtain characterization for boundedness of the weighted differentiation composition operator  from $Q_K(p,q) $ space into weighted Zygmund space.

Product of Composition and Multiplication Operator [PDF]

open access: yes, 1902
Operators are nothing but the mapping from a topological space to a topological space. When it satisfies the criterion for the linearity, it becomes linear.

The essential norm of a weighted composition operator on BMOA [PDF]

open access: yes, 2013
We consider weighted composition operators $${W_{\psi ,\varphi }}:f\mapsto \psi (f\circ \varphi )$$Wψ,φ:f↦ψ(f∘φ) on the space BMOA, which consists of the analytic functions on the unit disc whose boundary values have bounded mean oscillation on the unit ...

SUMS OF WEIGHTED COMPOSITION OPERATORS ON COP [PDF]

open access: yesGlasgow Mathematical Journal, 2012
AbstractLet COP =0∩H∞, where0is the little Bloch space on the open unit disk, andA() be the disk algebra on. For non-zero functionsu1,u2,. . .,uN∈A() and distinct analytic self-maps ϕ1,ϕ2,. . .,ϕNsatisfying ϕj∈A() and ∥ϕj∥∞=1 for everyj, it is given characterisations of which the sum of weighted composition operators ∑Nj=1ujCϕjmaps COP intoA().

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.

Spectrum of weighted composition operators. Part II: weighted composition operators on subspaces of Banach lattices [PDF]

open access: yesPositivity, 2012
We describe the spectrum of weighted $d$-isomorphisms of Banach lattices restricted on closed subspaces that are "rich" enough to preserve some "memory" of the order structure of the original lattice. The examples include (but are not limited to) weighted isometries of Hardy spaces on the polydisk and unit ball in $\mathds{C}^n$.

Topological Structures of Derivative Weighted Composition Operators on the Bergman Space

open access: yesJournal of Function Spaces, 2015
We characterize the difference of derivative weighted composition operators on the Bergman space in the unit disk and determine when linear-fractional derivative weighted composition operators belong to the same component of the space of derivative ...
