The Structure of Semiconic Idempotent Commutative Residuated Lattices
MathematicsIn this paper, we study semiconic idempotent commutative residuated lattices. After giving some properties of such residuated lattices, we obtain a structure theorem for semiconic idempotent commutative residuated lattices. As an application, we make use

Local spectral properties of commutators [PDF]
Proceedings of the Edinburgh Mathematical Society, 1995 For a pair of continuous linear operatorsTandSon complex Banach spacesXandY, respectively, this paper studies the local spectral properties of the commutatorC(S, T) given byC(S, T)(A): =SA−ATfor allA∈L(X, Y). Under suitable conditions onTandS, the main results provide the single valued extension property, a description of the local spectrum, and a ...

Centrally Essential Rings and Semirings
Mathematics, 2022 This paper is a survey of results on centrally essential rings and semirings. A ring (respectively, semiring) is said to be centrally essential if it is either commutative or satisfies the property that for any non-central element a, there exist non-zero

Tight Hardness of the Non-commutative Grothendieck Problem [PDF]
IEEE Annual Symposium on Foundations of Computer Science, 2014 We prove that it is NP-hard to approximate the non-commutative Grothendieck problem to within any constant factor larger than one-half, which matches the approximation ratio of the algorithm of Naor, Regev, and Vidick (STOC'13).

∇-prime rings and their commutativity
Journal of Taibah University for Science, 2023 Consider a ring with an (anti)-automorphism ∇ of finite order. The fundamental aim of this manuscript is to introduce the notions of ∇-(semi)prime ideal and ∇-(semi)prime ring as a generalization of the notions of (semi)prime ideal, [Formula: see text ...

A generalized Koszul property for skew PBW extensions [PDF]
, 2017 Let R be a commutative algebra. In this paper we show that constant skew PBW extensions of a generalized Koszul algebra R are also generalized Koszul. Let A be a semi-commutative skew PBW extension of R such that A is R-augmented.

Duality for Commutative Group Stacks [PDF]
International mathematics research notices, 2014 We study in this article the dual of a (strictly) commutative group stack $G$ and give some applications. Using the Picard functor and the Picard stack of $G$, we first give some sufficient conditions for $G$ to be dualizable.

Advanced Science, EarlyView.Lynch et al., identified novel targets on the wake‐promoting pathways that can effectively treat pain‐induced sleep disturbances. The authors demonstrated that Calcitonin gene‐related peptide‐expressing neurons (CGRP) in the external lateral parabrachial nucleus (PBelCGRP) serve as the primary relay node for pain stimuli that cause sleep disruption ...

On (α,β)-US Sets in BCK/BCI-Algebras
Mathematics, 2019 Molodtsov originated soft set theory, which followed a general mathematical framework for handling uncertainties, in which we encounter the data by affixing the parameterized factor during the information analysis. The aim of this paper is to establish a

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR
Advanced Intelligent Discovery, EarlyView.Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.
