Weighted composition operators from the Lipschitz space into the Zygmund space

, 2014
In this work, we give several characterizations of the bounded and the compact weighted composition operators from the Lipschitz space into the Zygmund space. Mathematics subject classification (2010): Primary 47B33; secondary 30H05.

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 ...

H(b) spaces of non-extreme b over finitely connected planar domains

Concrete Operators
In this work, density of the algebra A(D) $\mathcal{A}\left(D\right)$ in H(b) spaces of finitely connected planar domains and the boundedness of composition operators on these function spaces are studied.

Operator-weighted composition operators on vector-valued Bloch spaces

, 2018
Let φ be an analytic self-map of D and ψ be an analytic operator-valued function on D . Then the operator-weighted composition operator Wψ,φ is defined by (Wψ,φ f )(z) = ψ(z) f (φ(z)), z ∈ D, where f is an analytic function D → X , X is any complex ...

SUPERCYCLICITY OF TUPLES IN SOME TOPOLOGIES

, 2017
In this paper, we prove the supercylicity for a tuple of operators in the strong operator topology and in the norm of Hilbert-Schmidt operators. Also, the same result for hypercyclicity of tuples is considered.

SUPERCYCLICITY OF TUPLES IN THE HILBERT-SCHMIDT OPERATORS

, 2017
In this paper, we investigate the supercylicity for any tuple of operators in the class of Hilbert Schmidt operators. Also, the same result for hypercyclicity of tuples of operators is considered.

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

Generalized weighted composition operators from Bers-type spaces into Bloch-type spaces

, 2014
New criteria for the boundedness and the compactness of the generalized weighted composition operators from Bers-type spaces into Bloch-type spaces are given in this paper. Mathematics subject classification (2010): Primary 47B33, Secondary 30H30.
