On Commuting and Noncommuting Complexes [PDF]
Journal of Algebra, 2001 In this paper we study various simplicial complexes associated to the commutative structure of a finite group G. We define NC(G) (resp. C(G)) as the complex associated to the poset of pairwise non-commuting (resp. commuting) sets in G. We observe that NC(G) has only one positive dimensional connected component, which we call BNC(G), and we prove that ...

Commutators of singular integrals revisited [PDF]
Bulletin of the London Mathematical Society, 2017 We obtain a Bloom‐type characterization of the two‐weighted boundedness of iterated commutators of singular integrals. The necessity is established for a rather wide class of operators, providing a new result even in the unweighted setting for the first ...

T‐depth reduction method for efficient SHA‐256 quantum circuit construction
IET Information Security, Volume 17, Issue 1, Page 46-65, January 2023., 2023 Abstract To perform a quantum brute force attack on a cryptosystem based on Grover's algorithm, it is necessary to implement a quantum circuit of the cryptographic algorithm. Therefore, an efficient quantum circuit design of a given cryptographic algorithm is essential, especially in terms of quantum security analysis, and it is well known that T‐depth

A Method for Choosing an Initial Time Eigenstate in Classical and Quantum Systems
Entropy, 2013 A subject of interest in classical and quantum mechanics is the development of the appropriate treatment of the time variable. In this paper we introduce a method of choosing the initial time eigensurface and how this method can be used to generate time ...

Fractional operators and their commutators on generalized Orlicz spaces [PDF]
Opuscula Mathematica, 2022 In this paper we examine boundedness of fractional maximal operator. The main focus is on commutators and maximal commutators on generalized Orlicz spaces (also known as Musielak-Orlicz spaces) for fractional maximal functions and Riesz potentials.

A comprehensive analytical description of the asymmetric active snubber
IET Power Electronics, Volume 16, Issue 1, Page 102-117, 7 January 2023., 2023 Abstract Power modules for several hundred amperes suffer from a high stray inductance compared to discrete setups at similar current density. The use of silicon carbide in such modules is beneficial but due to the high stray inductance, the switching speed must be reduced to keep the voltage overshoot below breakdown voltage.

Open Mathematics, 2017 The main purpose of this paper is to prove that the boundedness of the commutator Mκ,b∗$\mathcal{M}_{\kappa,b}^{*} $ generated by the Littlewood-Paley operator Mκ∗$\mathcal{M}_{\kappa}^{*} $ and RBMO (μ) function on non-homogeneous metric measure ...

Some remarks on the sparse dominations for commutators of multi(sub)linear operator
Journal of Inequalities and Applications, 2021 We establish pointwise sparse dominations for the iterated commutators of multi(sub)linear operators satisfying the W q $W_{q}$ condition. As consequences, we present some quantitative weighted estimates for the commutators.

IET Renewable Power Generation, Volume 17, Issue 1, Page 95-109, 6 January 2023., 2023 Abstract Due to the complicated transients and the possibility of transition from a minor fault in AC subsystems to a severe blocking event of a high‐voltage direct–current (HVDC) transmission line, the study of AC‐DC hybrid power systems requires both efficient and accurate electromagnetic transient (EMT) simulation.

Journal of Inequalities and Applications, 2017 In this paper, we first introduce some new Morrey-type spaces containing generalized Morrey space and weighted Morrey space with two weights as special cases. Then we give the weighted strong type and weak type estimates for fractional integral operators
