Weighted estimates of higher order commutators generated by BMO-functions and the fractional integral operator on Morrey spaces

open access: yesJournal of Inequalities and Applications, 2016
The purpose of this paper is to investigate the weighted estimates of commutators generated by BMO-functions and the fractional integral operator on Morrey spaces. The main result generalizes the Sawano, Sugano, and Tanaka result to a weighted setting.

Making Almost Commuting Matrices Commute [PDF]

open access: yesCommunications in Mathematical Physics, 2009
Suppose two Hermitian matrices $A,B$ almost commute ($\Vert [A,B] \Vert \leq δ$). Are they close to a commuting pair of Hermitian matrices, $A',B'$, with $\Vert A-A' \Vert,\Vert B-B'\Vert \leq ε$? A theorem of H. Lin shows that this is uniformly true, in that for every $ε>0$ there exists a $δ>0$, independent of the size $N$ of the matrices, for ...

Commutator subgroup of Vershik–Kerov group

open access: yes, 2012
We describe a commutator subgroup of Vershik–Kerov group over an infinite field and find the bound for its commutator width. This gives a partial solution of the problem posed by Sushchanskii in 2010.

3-cycle commutator

open access: yes, 2020
We show within the maximum number of steps that if only one point is moved by two permutations, the commutator is a 3 ...

An Innovative Approach to Multi‐Valued Logic

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Characterizations for the genuine Calderón-Zygmund operators and commutators on generalized Orlicz-Morrey spaces

open access: yesAdvances in Nonlinear Analysis, 2023
In this article, we show continuity of commutators of Calderón-Zygmund operators [b,T]\left[b,T] with BMO functions in generalized Orlicz-Morrey spaces MΦ,φ(Rn){M}^{\Phi ,\varphi }\left({{\mathbb{R}}}^{n}). We give necessary and sufficient conditions for

Multiple commutator formulas

open access: yes, 2013
Let A be a quasi-finite R-algebra (i.e., a direct limit of module finite algebras) with identity. Let Ii, i = 0, . . . ,m, be two-sided ideals of A, GLn(A, Ii) be the principal congruence subgroup of level Ii in GLn(A) and En(A, Ii) be the relative ...

A Novel Converter Transformer DAM‐LSTNet Vibration Generation Model for Data Imbalance Identification

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformer vibration failures, primarily because of winding and core vibrations, severely impact the safe operation of high voltage direct current (HVDC) systems. These vibrations are influenced by voltage and current, and are transmitted through transformer oil and structural components to the tank. Current numerical models fail to

Lipschitz estimates for commutators of singular integral operators associated with the sections

open access: yesJournal of Inequalities and Applications, 2017
Let H be Monge-Ampère singular integral operator, b ∈ L i p F β $b\in Lip_{\mathcal{F}}^{\beta}$ , and 1 / q = 1 / p − β $1/q=1/p-\beta$ . It is proved that the commutator [ b , H ] $[b,H]$ is bounded from L p ( R n , d μ ) $L^{p}(\mathbb{R}^{n},d\mu ...
