Tests of Basic Quantum Mechanics in Oscillation Experiments [PDF]

, 1997
According to standard quantum theory, the time evolution operator of a quantum system is independent of the state of the system. One can, however, consider systems in which this is not the case: the evolution operator may depend on the density operator ...

A Dunkl type generalization of Szász operators via post-quantum calculus

Journal of Inequalities and Applications, 2018
The object of this paper to construct Dunkl type Szász operators via post-quantum calculus. We obtain some approximation results for these new operators and compute convergence of the operators by using the modulus of continuity.

Matrix Functions of Bounded Type: An Interplay Between Function Theory and Operator Theory [PDF]

Memoirs of the American Mathematical Society, 2016
In this paper, we study matrix functions of bounded type from the viewpoint of describing an interplay between function theory and operator theory. \ We first establish a criterion on the coprime-ness of two singular inner functions and obtain several ...

Approximation of Functions by Dunkl-Type Generalization of Szász-Durrmeyer Operators Based on p,q-Integers

Journal of Function Spaces, 2021
In this article, our main purpose is to define the p,q-variant of Szász-Durrmeyer type operators with the help of Dunkl generalization generated by an exponential function.

Genuine modified Bernstein–Durrmeyer operators

Journal of Inequalities and Applications, 2018
The present paper deals with genuine Bernstein–Durrmeyer operators which preserve some certain functions. The rate of convergence of new operators via a Peetre K $\mathcal{K}$-functional and corresponding modulus of smoothness, quantitative Voronovskaya ...

Construction of the Vacuum String Field Theory on a non-BPS Brane [PDF]

, 2002
In the framework of the Sen conjectures a construction of vacuum superstring field theory on a non-BPS brane is discussed. A distinguished feature of this theory is a presence of a ghost kinetic operator mixing GSO+/- sectors.

Extended Weyl-Type Theorems for Direct Sums

Demonstratio Mathematica, 2014
In this paper, we study the stability of extended Weyl and Browdertype theorems for orthogonal direct sum S⊕T, where S and T are bounded linear operators acting on Banach space.

Sequence spaces M ( ϕ ) $M(\phi)$ and N ( ϕ ) $N(\phi)$ with application in clustering

Journal of Inequalities and Applications, 2017
Distance measures play a central role in evolving the clustering technique. Due to the rich mathematical background and natural implementation of l p $l_{p}$ distance measures, researchers were motivated to use them in almost every clustering process ...

Generalization of Darbo-type theorem and application on existence of implicit fractional integral equations in tempered sequence spaces

Alexandria Engineering Journal, 2022
The aim of this work is to give some fixed point results based on the technique of measure of noncompactness which extend the classical Darbo’s theorem.

Epistemicism and modality [PDF]

, 2016
What kind of semantics should someone who accepts the epistemicist theory of vagueness defended in Timothy Williamson’s Vagueness (1994) give a definiteness operator?
