On the Lattice of $ES_I$-closed Classes of Multifunctions on Two-elements Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
The paper considers multifunctions on a two-element set with superposition and the equality predicate branching operator. The superposition operator is based on the intersection of sets. The main purpose of the work is to describe all closed classes with

Collapsing a perfect superposition to a chosen quantum state without measurement. [PDF]

open access: yesPLoS ONE, 2014
Given a perfect superposition of [Formula: see text] states on a quantum system of [Formula: see text] qubits. We propose a fast quantum algorithm for collapsing the perfect superposition to a chosen quantum state [Formula: see text] without applying any

Integral Superposition-Type Operators on Some Analytic Function Spaces

open access: yesJournal of Function Spaces, 2021
All entire functions which transform a class of holomorphic Zygmund-type spaces into weighted analytic Bloch space using the so-called n-generalized superposition operator are characterized in this paper.

On some properties of the superposition operator on topological manifolds [PDF]

open access: yesOpuscula Mathematica, 2010
In this paper the superposition operator in the space of vector-valued, bounded and continuous functions on a topological manifold is considered. The acting conditions and criteria of continuity and compactness are established.

On solutions of some delay Volterra integral problems on a half-line

open access: yesNonlinear Analysis, 2021
In this paper, we study the existence of a.e. monotonic solutions of some general delay integral problems for both fractional and integer orders in the space of Lebesgue integrable functions on the interval R+ = [0;1) and in the space of locally ...

Coherent and incoherent superposition of transition matrix elements of the squeezing operator

open access: yesNew Journal of Physics, 2022
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnetic radiation).

Some inequalities and superposition operator in the space of regulated functions

open access: yesAdvances in Nonlinear Analysis, 2019
Some inequalities connected to measures of noncompactness in the space of regulated function R(J, E) were proved in the paper. The inequalities are analogous of well known estimations for Hausdorff measure and the space of continuous functions.

Uniformly Continuous Superposition Operators In The Space Of Functions Of Bounded n-Dimensional Φ-Variation

open access: yesDemonstratio Mathematica, 2014
We prove that if a superposition operator maps a subset of the space of all metric-vector-space-valued-functions of bounded n-dimensional Φ-variation into another such space, and is uniformly continuous, then the generating function of the operator is an

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
