Weighted composition operator valued integral [PDF]
, 2017 In the paper we are going to introduce a weighted composition operator-valued integral on L2(X) with a weakly integrable weight function u and we will consider some classic properties of these kind operators.Then we will give the necessary and ...

On the closed range problem for composition operators on the Dirichlet space
Concrete Operators, 2019 We characterize closed range composition operators on the Dirichlet space for a particular class of composition symbols. The characterization relies on a result about Fredholm Toeplitz operators with BMO1 symbols, and with Berezin transforms of vanishing

Kitai's Criterion for composition operators
Journal of Mathematical Analysis and ApplicationsWe present a general and natural framework to study the dynamics of composition operators on spaces of measurable functions, in which we then reconsider the characterizations for hypercyclic and mixing composition operators obtained by Bayart, Darji and Pires.

A Composition Operator for Systems with Active and Passive Actions [PDF]
, 2005 We investigate requirements for a composition operator for complex control systems. The operator should be suitable for a context where we have both supervisory control and a system that consists of multiple (two or more) components.

Demonstratio MathematicaThis article presents a characterization of non-singular measurable transformation, denoted as TT, mapping from Ω\Omega to itself, along with bicomplex-valued BC{\mathbb{BC}}-measurable function uu defined on Ω\Omega , which induces a weighted ...

Boundedness of composition operators on Morrey spaces and weak Morrey spaces
Journal of Inequalities and Applications, 2021 In this study, we investigate the boundedness of composition operators acting on Morrey spaces and weak Morrey spaces. The primary aim of this study is to investigate a necessary and sufficient condition on the boundedness of the composition operator ...

Uniformly continuous composition operators in the space of bounded Φ-variation functions in the Schramm sense [PDF]
Opuscula Mathematica, 2012 We prove that any uniformly continuous Nemytskii composition operator in the space of functions of bounded generalized \(\Phi\)-variation in the Schramm sense is affine. A composition operator is locally defined.

Some Estimates of Integrals with a Composition Operator [PDF]
, 2010 We give some estimates of integrals with a composition operator, namely, composition of homotopy, differential, and Green's operators T∘d∘G, with the Lipschitz and BMO norms.

Classification of Multioperations of Rank 2 by E-precomplete Sets
Известия Иркутского государственного университета: Серия "Математика", 2020 In this paper multioperations defined on a two-element set and their closure operator based on composition operator and the equality predicate branching operator is considered. The composition operator is based on union of sets.
