On the structure of some left braces [PDF]

open access: yesInternational Journal of Group Theory, 2023
Given an element $a$ of a left brace $A$ satisfying some nilpotency conditions, we describe the smallest subbrace of $A$ containing~$a$. We also present a description of the left braces satisfying the minimal condition for subbraces.

The Uncertainty Principle and the Minimal Space–Time Length Element

open access: yesPhysics, 2022
Quantum gravity theories rely on a minimal measurable length for their formulations, which clashes with the classical formulation of the uncertainty principle and with Lorentz invariance from general relativity.

The Characteristic of the Minimal Ideals and the Minimal Generalized Ideals in Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2023
In this paper, we prove that the characteristic of a minimal ideal and a minimal generalized ideal, which is meant to be one of minimal left ideal, minimal right ideal, bi-ideal, quasi-ideal, and m,n-ideal in a ring, is either zero or a prime number p ...

Real Elements and p-Nilpotence of Finite Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
Our first main result proves that every element of order 4 of a Sylow 2-subgroup S of a minimal non-2-nilpotent group G, is a real element of S. This allows to give a character-free proof of a theorem due to Isaacs and Navarro (see [9, Theorem B]). As an

An extended inequality approach for evaluating decision making units with a single output

open access: yesJournal of Inequalities and Applications, 2017
In this work, an extended evaluation approach for decision making units (DMUs) with a single output is proposed. Firstly, the input and output data for each DMU are changed in the same proportion until all the outputs are equal, and then the coordinate ...

On the second spectrum of lattice modules

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
The second spectrum Specs(M) is the collection of all second elements of M. In this paper, we study the topology on Specs(M), which is a generalization of the Zariski topology on the prime spectrum of lattice modules. Besides some properties, Specs(M) is

On Weights Which Admit Harmonic Bergman Kernel and Minimal Solutions of Laplace’s Equation

open access: yesAnnales Mathematicae Silesianae, 2022
In this paper we consider spaces of weight square-integrable and harmonic functions L2H(Ω, µ). Weights µ for which there exists reproducing kernel of L2H(Ω, µ) are named ’admissible weights’ and such kernels are named ’harmonic Bergman kernels’. We prove
