Infinitesimal Carleson property for weighted measures induced by analytic self-maps of the unit disk [PDF]
, 2012 We prove that, for every $\alpha > -1$, the pull-back measure $\phi ({\cal A}_\alpha)$ of the measure $d{\cal A}_\alpha (z) = (\alpha + 1) (1 - |z|^2)^\alpha \, d{\cal A} (z)$, where ${\cal A}$ is the normalized area measure on the unit disk $\D$, by ...

Essential norm of the differences of composition operators on the Bloch space
, 2017 We provide some estimates for the essential norm of the differences of composition operators Cφ −Cψ acting on the Bloch space by using pseudo-hyperbolic distance, Möbius transformation and φn −ψn . Mathematics subject classification (2010): 30H30, 47B33.

Weighted composition operators from Dirichlet-type spaces into Stević-type spaces
, 2020 The boundedness and compactness of weighted composition operators from Dirichlettype spaces into Stević-type spaces are investigated in this paper. Some estimates for the essential norm of weighted composition operators are also given.

Compact composition operators on Bergman-Orlicz spaces [PDF]
, 2009 We construct an analytic self-map ' of the unit disk and an Orlicz functionfor which the composition operator of symbol ' is compact on the Hardy-Orlicz space H , but not on the Bergman-Orlicz space B .

On the compactness of the Stević-Sharma operator on the logarithmic Bloch spaces
, 2016 Let H(D) denote the space of all analytic functions on the unit disc D of the complex plane C , ψ1,ψ2 ∈ H(D) , and φ be an analytic self-map of D . In this paper, we characterize the compactness of the Stević-Sharma operator on the logarithmic Bloch ...

Weighted composition operators between Lipschitz spaces on pointed metric spaces
Operators and Matrices, 2019 In this paper, we study weighted composition operators between Banach spaces of scalar-valued Lipschitz functions on pointed metric spaces, not necessarily compact.

Composition operators and closures of Dirichlet type spaces in logarithmic Bloch-type spaces
Journal of Mathematical Inequalities, 2020 Closures of Dirichlet type spaces in logarithmic Bloch-type spaces are investigated in the paper. Moreover, the boundedness and compactness of composition operators from logarithmic Bloch-type spaces to closures of Dirichlet type spaces in logarithmic ...

Approximation and entropy numbers of composition operators
Concrete Operators, 2020 We give a survey on approximation numbers of composition operators on the Hardy space, on the disk and on the polydisk, and add corresponding new results on their entropy numbers, revealing how they are different.

Hardy spaces of generalized analytic functions and composition operators
Concrete Operators, 2018 We present some recent results on Hardy spaces of generalized analytic functions on D specifying their link with the analytic Hardy spaces. Their definition can be extended to more general domains Ω . We discuss the way to extend such definitions to more
