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.

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.

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.

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.

Wielandt′s Theorem and Finite Groups with Every Non-nilpotent Maximal Subgroup with Prime Index

open access: yesJournal of Harbin University of Science and Technology, 2023
In order to give a further study of the solvability of a finite group in which every non-nilpotent maximal subgroup has prime index, the methods of the proof by contradiction and the counterexample of the smallest order and a theorem of Wielandt on the ...

Polynomial sequences in discrete nilpotent groups of step 2

open access: yesAdvanced Nonlinear Studies, 2023
We discuss some of our work on averages along polynomial sequences in nilpotent groups of step 2. Our main results include boundedness of associated maximal functions and singular integrals operators, an almost everywhere pointwise convergence theorem ...

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 ...

Nilpotent Fuzzy Subgroups

open access: yesMathematics, 2018
In this paper, we introduce a new definition for nilpotent fuzzy subgroups, which is called the good nilpotent fuzzy subgroup or briefly g-nilpotent fuzzy subgroup.

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 $p=2$‎.
