On the dynamics of weighted composition operators
Journal of Mathematical Analysis and ApplicationsWe study the properties of power-boundedness, Li-Yorke chaos, distributional chaos, absolutely Cesàro boundedness and mean Li-Yorke chaos for weighted composition operators on $L^p(μ)$ spaces and on $C_0(Ω)$ spaces. We illustrate the general results by presenting several applications to weighted shifts on the classical sequence spaces $c_0(\mathbb{N})$,

Generators of C0-semigroups of weighted composition operators
Israel Journal of Mathematics, 2022 We prove that in a large class of Banach spaces of analytic functions in the unit disc $\mathbb{D}$ an (unbounded) operator $Af=G\cdot f'+g\cdot f$ with $G,\, g$ analytic in $\mathbb{D}$ generates a $C_0$-semigroup of weighted composition operators if and only if it generates a $C_0$-semigroup.

Weighted composition operators from the Bloch space to weighted Banach spaces on bounded homogeneous domains [PDF]
, 2022 We study the bounded and the compact weighted composition operators from the Bloch space into the weighted Banach spaces of holomorphic functions on bounded homogeneous domains, with particular attention to the unit polydisk.

Spectra of Weighted Composition Operators with Quadratic Symbols
Concrete Operators, 2022 Previously, spectra of certain weighted composition operators W ѱ, φ on H2 were determined under one of two hypotheses: either φ converges under iteration to the Denjoy-Wolff point uniformly on all of 𝔻 rather than simply on compact subsets, or φ is ...

Weighted Composition Operators Between Different Fock Spaces [PDF]
, 2018 We study weighted composition operators acting between Fock spaces. The following results are obtained: (i) Criteria for the boundedness and compactness. (ii) Characterizations of compact differences and essential norm.

Compact Weighted Composition Operators and Multiplication Operators between Hardy Spaces
Abstract and Applied Analysis, 2008 We estimate the essential norm of a compact weighted composition operator 𝑢𝐶𝜑 acting between different Hardy spaces of the unit ball in ℂ𝑁. Also we will discuss a compact multiplication operator between Hardy spaces.

The composition operators on weighted Bloch space [PDF]
Archiv der Mathematik, 2002 Let \(H(D)\) denote the set of all holomorphic functions in the open unit disk \(D\) and let \(\phi\) be a holomorphic selfmap of \(D\). Suppose that \(X\) and \(Y\) are two function spaces defined on \(D\). The map \(\phi\) is said to have the \(X\)-to-\(Y\) pullback property if \(f\circ \phi\in Y\) for every \(f\in X\).

The spectra of linear fractional composition operators on weighted Dirichlet spaces [PDF]
, 2016 We completely determine the spectra of composition operators induced by linear fractional self-maps of the unit disc acting on weighted Dirichlet spaces; extending earlier results by Higdon [8] and answering the open questions in this context.Ministerio ...

Composition operators on Banach function spaces [PDF]
, 2013 The aim of this thesis is to provide a survey of the topic of composition operators on spaces of (equivalence classes of) measurable functions and attempt to unify some of the most important results contained in the literature.
