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.

Compact differences of weighted composition operators [PDF]

open access: yesCollectanea Mathematica, 2020
AbstractCompact differences of two weighted composition operators acting from the weighted Bergman space $$A^p_{\omega }$$ A ω p to another weighted Bergman space $$A^q_{\nu }$$ A ...

Composition-Differentiation Operator on Weighted Bergman Spaces [PDF]

open access: yes, 2023
In this paper, we study the complex symmetry of weighted composition-differentiation operator $D_{n, \psi, \phi}$ on weighted Bergman spaces $\mathcal{A}^2_{\alpha}$ with respect to the conjugation $C_{\mu, \eta}$ for $\mu, \eta \in \{z\in \mathbb{C}:|z|=

Complex symmetric weighted composition operators on the Hardy space [PDF]

open access: yes, 2020
summary:This paper identifies a class of complex symmetric weighted composition operators on $H^2(\mathbb {D})$ that includes both the unitary and the Hermitian weighted composition operators, as well as a class of normal weighted composition operators ...

Weighted Composition Operators on BMOA [PDF]

open access: yesComputational Methods and Function Theory, 2008
The author completely characterizes the boundedness and compactness of the weighted composition operator \(W_{\psi,\varphi}f=\psi (f\circ \varphi)\) acting on \(BMOA\) and \(VMOA\) of the unit disc. The results extend and unify those known for the cases \(\varphi(z)=z\) and \(\psi(z)=1\) corresponding to the multiplication operator \(M_\psi\) [see ...

Rigidity of weighted composition operators on H^p

open access: yesAnnales Academiae Scientiarum Fennicae Mathematica, 2020
We show that every non-compact weighted composition operator $f \mapsto u\cdot (f\circϕ)$ acting on a Hardy space $H^p$ for $1 \leq p < \infty$ fixes an isomorphic copy of the sequence space $\ell^p$ and therefore fails to be strictly singular. We also characterize those weighted composition operators on $H^p$ which fix a copy of the Hilbert space $\

A sufficient condition for the boundedness of operator-weighted martingale transforms and Hilbert transform [PDF]

open access: yes, 2007
Let W be an operator weight taking values almost everywhere in the bounded positive invertible linear operators on a separable Hilbert space H. We show that if W and its inverse W−1 both satisfy a matrix reverse Holder property introduced in [2], then ...

Invertible and Isometric Weighted Composition Operators

open access: yesMediterranean 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 ...

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 $\mathds{C}^n$.
