Generalized derivations as homomorphisms or anti-homomorphisms on Lie ideals

open access: yesArab Journal of Mathematical Sciences, 2016
Let R be a prime ring of char(R)≠2, Z the center of R, and L a nonzero Lie ideal of R. If R admits a generalized derivation F associated with a derivation d which acts as a homomorphism or as anti-homomorphism on L, then either d=0 or L⊆Z.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Characterization of Multiplicative Lie Triple Derivations on Rings

open access: yesAbstract and Applied Analysis, 2014
Let R be a ring having unit 1. Denote by ZR the center of R. Assume that the characteristic of R is not 2 and there is an idempotent element e∈R such that aRe=0⇒a=0  and  aR1-e=0⇒a=0.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

On a conjecture on transposed Poisson n-Lie algebras

open access: yesAIMS Mathematics
The notion of a transposed Poisson $ n $-Lie algebra has been developed as a natural generalization of a transposed Poisson algebra. It was conjectured that a transposed Poisson $ n $-Lie algebra with a derivation gives rise to a transposed Poisson $ (n ...

Generalized Derivations of Lie Algebras

open access: yesJournal of Algebra, 2000
Let \(L\) be a finite dimensional Lie algebra with multiplication given by \(\mu\). The authors study the generalized derivations of \(L\), \(\text{GenDer}(L)\), consisting of the elements \(f\in\Hom(L,L)\) such that there exist \(f',f''\in\Hom(L,L)\) satisfying \(\mu(f(x),y)+\mu(x,f'(y))=f''(\mu(x,y))\) for all \(x,y\in L\).

Generalized Lie derivations of unital algebras with idempotents

open access: yes, 2018
Let A be a unital algebra with a nontrivial idempotent e over a unital commutative ring R . We show that under suitable assumptions every generalized Lie n -derivation F : A → A is of the form F(x) = λx+ Δ(x) , where λ ∈ Z(A ) and Δ is a Lie n ...

On n-Derivations and n-Homomorphisms in Perfect Lie Superalgebras

open access: yesMathematics
Let n≥2 be a fixed integer. The aim of this paper is to investigate the properties of n-derivations within the framework of perfect Lie superalgebras over a commutative ring R. The main result shows that if the base ring contains 1n−1, and L is a perfect
