Composition Operators Belonging to Operator Ideals [PDF]

Journal of Mathematical Analysis and Applications, 1999
Let \(D\) be the unit disc \(\{z\in\mathbb{C}:|z|< 1\}\) of the complex plane \(\mathbb{C}\), and let \(\mu\) be the normalized Lebesgue measure on \(D\).

The Composition Operator Induced By The Function

Journal of Kufa for Mathematics and Computer, 2012
The main aim of this search to study the composition operator induced by the automorphism  and discuss the adjoint of the composition operator, also we discuss some properties of composition operator and tried to see the analogue properties in order to

Cyclic Composition operators on Segal-Bargmann space

Concrete Operators, 2022
We study the cyclic, supercyclic and hypercyclic properties of a composition operator Cϕ on the Segal-Bargmann space ℋ(ℰ), where ϕ(z) = Az + b, A is a bounded linear operator on ℰ, b ∈ ℰ with ||A|| ⩽ 1 and A*b belongs to the range of (I – A*A)½ ...

Composition Operators and Endomorphisms [PDF]

Complex Analysis and Operator Theory, 2010
If $b$ is an inner function, then composition with $b$ induces an endomorphism, $β$, of $L^\infty(\mathbb{T})$ that leaves $H^\infty(\mathbb{T})$ invariant. We investigate the structure of the endomorphisms of $B(L^2(\mathbb{T}))$ and $B(H^2(\mathbb{T}))$ that implement $β$ through the representations of $L^\infty(\mathbb{T})$ and $H^\infty(\mathbb{T})$

Maximal functions and subordination for operator groups. [PDF]

, 2002
Let E be a UMD Banach space and L a positive and self-adjoint operator in L^2 of Laplace type such that the imaginary powers L^{-it} form a C_0 group of exponential growth on L^p(E).

Composition Operators on Classical Spaces of Analytic Functions [PDF]

Sahand Communications in Mathematical Analysis
We shall provide a brief account on new achievements in the study of composition and composition-differentiation operators acting on classical spaces of analytic functions on the unit disk, as well as on the polydisk and the unit ball.

PROPERTIES AND APPLICATIONS OF THE COMPOSITION OPERATOR BETWEEN CERTAIN FUNCTION SPACES. [PDF]

Alfarama Journal of Basic & Applied Sciences, 2023
In this study, we aim to investigate the boundedness and compactness of the composition operator $C_\Theta$, and to provide characterizations of its boundedness and compactness.We introduce necessary conditions and sufficient conditions for the operator $

Cyclic behaviour of Volterra composition operators [PDF]

, 2011
We determine the cyclic behaviour of Volterra composition operators, which are defined as $(V_\phif)(x) =\int_0^{\phi(x)}f(t) dt$, $f ? L^p[0, 1]$, 1\leq p <\infty$,where $?$ is a measurable self-map of [0, 1].
