Boundedness and continuity of superposition operator on Er(p) and Fr(p) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2002
Let X ∈ {Er(p)V , Fr(p)}, in this research, necessary and sufficient conditions are given for superposition operator to act from X into the space l1. Moreover, necessary and sufficient conditions are obtained for superposition operator acting from X into

Analytic Morrey Spaces and Bloch-Type Spaces

open access: yesJournal of Function Spaces, 2018
This paper is devoted to characterizing the boundedness of the Riemann-Stieltjes operators from analytic Morrey spaces to Bloch-type spaces. Moreover, the boundedness of the superposition operator and weighted composition operator on analytic Morrey ...

Formation of required distributions on the basis of decomposition by vortex eigen functions of a bounded non-paraxial propagation operator [PDF]

open access: yesКомпьютерная оптика, 2019
The solution of the problem of overcoming the diffraction limit based on the representation of an optical signal in the form of a superposition of communication modes matched with the vortex eigenfunctions of a bounded (in the object and spectral regions)

Superposition operators on Dirichlet spaces [PDF]

open access: yesTohoku Mathematical Journal, 2004
Let \((\mathcal E, \mathcal D)\) be a strongly local, regular symmetric Dirichlet form. A function \(K\) is said to operate on \(\mathcal D\), if \(K\circ u \in \mathcal D\) for all \(u\in\mathcal D\). By the very definition of Dirichlet forms all normal contractions operate on \(\mathcal D\) and satisfy \(\mathcal E(K\circ u,K\circ u) \leq M^2\cdot ...

Macroscopicity of quantum superpositions on a one-parameter unitary path in Hilbert space [PDF]

open access: yes, 2014
We analyze quantum states formed as superpositions of an initial pure product state and its image under local unitary evolution, using two measurement-based measures of superposition size: one based on the optimal quantum binary distinguishability of the

Quantum conformal symmetries for spacetimes in superposition [PDF]

open access: yesQuantum
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical and experimental investigations.

Weighted superposition operators on Fock spaces [PDF]

open access: yesRevista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2022
AbstractWe characterize all pairs of entire functions $$(u,\psi )$$ ( u , ψ ) for which the induced weighted superposition operator $$S_{(u,\psi )}$$ S

Consistent use of paradoxes in deriving constraints on the dynamics of physical systems and of no-go-theorems [PDF]

open access: yes, 1995
The classical methods used by recursion theory and formal logic to block paradoxes do not work in quantum information theory. Since quantum information can exist as a coherent superposition of the classical ``yes'' and ``no'' states, certain tasks which ...

The superposition operator in the space of functions continuous and converging at infinity on the real half-axis

open access: yesAdvances in Nonlinear Analysis, 2019
We will consider the so-called superposition operator in the space CC(ℝ+) of real functions defined, continuous on the real half-axis ℝ+ and converging to finite limits at infinity.

The measurement problem in quantum mechanics

open access: yesScience & Philosophy, 2019
In this paper, we discuss the importance of measurement in quantum mechanics and the so-called measurement problem. Any quantum system can be described as a linear combination of eigenstates of an operator representing a physical quantity; this means ...
