n-complete crossed modules and wreath products of groups
Journal of New Results in Science, 2021 In this paper we examine the $n$-completeness of a crossed module and we show that if $X=(W_1,W_2,\partial)$ is an $n$-complete crossed module, where $W_i=A_i wr B_i$ is the wreath product of groups $A_i$ and $B_i$, then $A_i$ is at most $n$-complete ...

Non-Commutative Representations of Families of k^2 Commutative Polynomials in 2k^2 Commuting Variables [PDF]
arXiv, 2012 Given a collection P of k^2 commutative polynomials in 2k^2 commutative variables, the objective is to find a condensed representation of these polynomials in terms of a single non-commutative polynomial p(X,Y) in two k x k matrix variables X and Y.

Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons
Advanced Quantum Technologies, EarlyView.Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware
Advanced Quantum Technologies, EarlyView.Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Noncompact commutators in the commutant of a cyclic operator [PDF]
Proceedings of the American Mathematical Society, 1989 We show that the commutant of the operator S ⊗ ( I + S ∗ ) S \otimes \left ( {I + {S^*}} \right ) , where S S is the shift operator, contains two operators

The Commutator of Two Fuzzy Subsets
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 In this paper we introduce the idea of the commutator of two fuzzy subsets of a group and study the concept of the commutator of two fuzzy subsets of a group .We introduce and study some of its properties .

Some properties of pseudomeadows [PDF]
arXiv, 2020 The purpose of this paper is to study the commutative pseudomeadows, the structure which is defined in the same way as commutative meadows, except that the existence of a multiplicative identity is not required. We extend the characterization of finite commutative meadows, given by I.~Bethke, P.~Rodenburg, and A.~Sevenster in their 2015 paper, to the ...

CIDADES, Comunidades e Territórios, 2023 It is inadequate that the phrase “women in architecture” embeds primarily the names of unknown or long forgotten female architects, or refers to contemporary female architects who are labelled and therefore indefinably distinguished from other professionals in their field.
