On the range of composition operators on spaces of entire functions

, 2011
The celebrated Paley-Wiener theorem naturally identifies the spaces of bandlimited functions with subspaces of entire functions of exponential type. Recently, it has been shown that these spaces remain invariant only under composition with affine maps ...

Study of weighted elliptic composition operators on the unit ball of ℂN

Concrete Operators
We study the general properties, point spectrum and spectrum of a weighted composition operator Wm,φ{W}_{m,\varphi } with elliptic symbol φ\varphi on the unit ball BN{{\mathbb{B}}}_{N} of CN{{\mathbb{C}}}^{N}, and general weight m∈Hol(BN)m\in {\rm{Hol}}\

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.

Operators commuting with complex symmetric weighted composition operators on H 2

Concrete Operators
In this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

A note on the Königs domain of compact composition operators on the Bloch space

Journal of Inequalities and Applications, 2011
Let be the unit disk in the complex plane. We define to be the little Bloch space of functions f analytic in which satisfy lim|z|→1 (1 - |z|2)|f'(z)| = 0. If is analytic then the composition operator Cφ : f ↦ f ∘ φ

Norms and essential norms of composition operators from H^∞ to general weighted Bloch spaces in the polydisk

Journal of Inequalities and Applications, 2011
Let Un be the unit polydisk of ℂ n and φ a holomorphic self-map of Un. H∞(Un) and B log α ( U n ) denote the space of bounded holomorphic functions and the space of general weighted Bloch functions ...
