The Change of the Supervision of the Activities of Economic Operators
Teisė, 2021 The present article analyses the essence and purpose of the supervision of the activities of economic operators as a field of public administration, as well as its expression and evaluation in national administrative law.

A relative of the shift operator
Linear Algebra and its Applications, 1992 For a positive number \(\alpha\), define \(E_ \alpha\) by \[ E_ \alpha=\{\lambda\in \mathbb{C}:\;| \lambda-1|+|\lambda +1|\leq \alpha+\alpha^{-1}\}. \] For \(\alpha\neq 1\), \(E_ \alpha\) is a closed elliptic disc. If \(U\) is the unilateral shift on a Hilbert space \(H\), then for any complex number \(\alpha\) define \(U_ \alpha\) by \(U_ \alpha={1 ...

Commutator Anomaly in Noncommutative Quantum Mechanics
, 2005 In this letter, firstly, the Schr$\ddot{o}$dinger equation on noncommutative phase space is given by using a generalized Bopp's shift. Then the anomaly term of commutator of arbitrary physical observable operators on noncommutative phase space is ...

Journal of Mathematical Analysis and Applications, 1988 Let X be a Banach space. An operator T on X is called a Gellar basis shift if there is a scalar sequence \(\{W_ n\}\) and a normalized basis \(\{x_ n\}\) of X such that \(Tx_ n=w_ nx_{n+1}\). In this case, we say that the basis \(\{x_ n\}\) is Gellar shiftable by T. An operator T on X is said to be a Crownover shift if T is injective, has closed range,

Shift operators on Banach spaces
Journal of Functional Analysis, 1991 The authors discuss the question as to which Banach spaces admit a shift operator. They show that if a compact Hausdorff space \(X\) is not separable and has no isolated points then the Banach space \(C(x)\) does not admit an isometric shift. They also discuss shift operators on Dedekind complete Banach lattices, and establish that these spaces do not ...

Quantum Walks with Entangled Coins
, 2004 We present a mathematical formalism for the description of unrestricted quantum walks with entangled coins and one walker. The numerical behaviour of such walks is examined when using a Bell state as the initial coin state, two different coin operators ...

Sequences of twice-iterated Δw-Gould–Hopper Appell polynomials
Journal of Taibah University for ScienceIn this paper, we introduce general sequence of twice-iterated [Formula: see text]-(degenerate) Gould–Hopper Appell polynomials (TI-DGHAP) via discrete [Formula: see text]-Gould–Hopper Appell convolution. We obtain some of their characteristic properties

Personality risk factors in assessing the reliability of the performance of operating personnel
European Psychiatry, 2021 Introduction The development of complex human-machine systems has led to greater demands on operators’ skills, and has increased the importance of human error (Pribytkova et al, 2012; Vondráčková et al, 2017; Jian Ai Yeow, 2014).

Hypercyclic operators on Lipschitz spaces [PDF]
Математичні Студії, 2013 We consider hypercyclic operators on free Banach spaces and little Lipschitz spaces which are some kind of generalizations of shift operators and composition operators respectively.
