Nilpotent Graph

open access: yesTheory and Applications of Graphs, 2021
In this article, we introduce the concept of nilpotent graph of a finite commutative ring. The set of all non nilpotent elements of a ring is taken as the vertex set and two vertices are adjacent if and only if their sum is nilpotent.

Ricci-flat and Einstein pseudoriemannian nilmanifolds

open access: yesComplex Manifolds, 2019
This is partly an expository paper, where the authors’ work on pseudoriemannian Einstein metrics on nilpotent Lie groups is reviewed. A new criterion is given for the existence of a diagonal Einstein metric on a nice nilpotent Lie group.

Omegas of agemos in powerful groups [PDF]

open access: yesInternational Journal of Group Theory, 2020
In this note we show that for any powerful $p$-group $G$‎, ‎the subgroup‎ ‎$\Omega_{i}(G^{p^{j}})$ is powerfully nilpotent for all $i,j\geq1$‎ ‎when $p$ is an odd prime‎, ‎and $i\geq1$‎, ‎$j\geq2$ when $p=2$‎.

Chimera state in coupled map lattice of matrices

open access: yesLietuvos Matematikos Rinkinys, 2021
In recent years, a lot of research has focused on understanding the behavior of when synchronous and asynchronous phases occur, that is, the existence of chimera states in various networks.

Semi Nilpotent Elements [PDF]

open access: yesEurasian Journal of Science and Engineering, 2017
In this paper we study semi nilpotent elements in rings. It is shown that every element of Z nwhere n is square free is a trivial semi nilpotent. It is proved that every nontrivial nilpotent element is a nontrivial semi nilpotent.

On the formal power series algebras generated by a vector space and a linear functional [PDF]

open access: yesJournal of Hyperstructures, 2017
Let R be a vector space ( on C) and ϕ be an element of R∗ (the dual space of R), the product r · s = ϕ(r)s converts R into an associative algebra that we denote it by Rϕ.

Commutative Medial Near Ring

open access: yesRatio Mathematica, 2023
We deliberate a substructure of a near ring called mediality so as to create a new platform, on which many of the properties like commutativity, regular, idempotent and zero symmetric are applied with.

Study Some Properties of a Circulant Matrix

open access: yesTikrit Journal of Pure Science, 2023
The aim of this paper is to study the properties of idempotent, nilpotent and stability to a circulant matrix  which generated by the first row, finally we showed the relation between this properties with eigenvalues of this matrix.

On classification of (n + 6)-dimensional nilpotent n-Lie algebras of class 2 with n ≥ 4 [PDF]

open access: yesArab Journal of Mathematical Sciences, 2021
Purpose – The purpose of this paper is to determine the structure of nilpotent (n+6)-dimensional n-Lie algebras of class 2 when n≥4. Design/methodology/approach – By dividing a nilpotent (n+6)-dimensional n-Lie algebra of class 2 by a central element ...
