On free subgroups of finite exponent in circle groups of free nilpotent algebras [PDF]

open access: yesInternational Journal of Group Theory, 2019
‎Let $K$ be a commutative ring with identity and $N$ the free nilpotent $K$-algebra on a non-empty set $X$‎. ‎Then $N$ is a group with respect to the circle composition‎. ‎We prove that the subgroup generated by $X$ is relatively free in a suitable class

Generalized projections in

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
We consider the ring (integers modulo ) with the partial order ‘’ given by ‘ if either or ’. In this paper, we obtain necessary and sufficient conditions for the poset () to be a lattice.

The Source of Primeness of Rings

open access: yesJournal of New Theory, 2022
In this study, we define a new concept, i.e., source of primeness of a ring $R$, as $P_{R} := \bigcap_{a\in R} S_{R}^{a}$ such that $S_{R}^{a}:=\{b\in R \mid aRb=(0)\}$.

A Note on Skew Generalized Power Serieswise Reversible Property

open access: yesInternational Journal of Analysis and Applications, 2023
The aim of this paper is to introduce and study (S, ω)-nil-reversible rings wherein we call a ring R is (S, ω)-nil-reversible if the left and right annihilators of every nilpotent element of R are equal.

Logarithmic W-algebras and Argyres-Douglas theories at higher rank

open access: yesJournal of High Energy Physics, 2018
Families of vertex algebras associated to nilpotent elements of simply-laced Lie algebras are constructed. These algebras are close cousins of logarithmic W-algebras of Feigin and Tipunin and they are also obtained as modifications of semiclassical ...

B-Fredholm elements in primitive C*-algebras

open access: yesOpen Mathematics, 2022
Let A{\mathcal{A}} be a unital primitive C∗\ast -algebra. This article studies the properties of the B-Fredholm elements, the B-Weyl elements and the B-Browder elements in A{\mathcal{A}}. Particularly, this article describes the B-Fredholm element as the

On the derivations of Leibniz algebras of low dimension

open access: yesДоповiдi Нацiональної академiї наук України, 2023
Let L be an algebra over a field F. Then L is called a left Leibniz algebra if its multiplication operations [×, ×] addition- ally satisfy the so-called left Leibniz identity: [[a,b],c] = [a,[b,c]] – [b,[a,c]] for all elements a, b, c Î L. In this paper,

Engel BCI-algebras: an application of left and right commutators [PDF]

open access: yesMathematica Bohemica, 2021
We introduce Engel elements in a BCI-algebra by using left and right normed commutators, and some properties of these elements are studied. The notion of $n$-Engel BCI-algebra as a natural generalization of commutative BCI-algebras is introduced, and we ...

Natural Filtrations of Infinite-Dimensional Modular Contact Superalgebras

open access: yesJournal of Applied Mathematics, 2014
The natural filtration of the infinite-dimensional contact superalgebra over an algebraic closed field of positive characteristic is proved to be invariant under automorphisms by characterizing ad-nilpotent elements and the subalgebras generated by ...

Nilpotent elements in physics [PDF]

open access: yesJournal of Physical Studies, 2007
Institute of Theoretical Physics, University of Wroclaw,pl. M. Borna 9, 50–204 Wroclaw, Poland(Received January 4, 2007)We briefly review some issues of the nilpotent objects in theoretical physics using simple modelsas an illustration. Nilpotent elements appear at quantum and classical level in several ways.
