Engel conditions and symmetric tensors [PDF]
Linear and Multilinear Algebra, 2011 In a recent study of Engel Lie rings, Serena Cicalo` and Willem de Graaf have given a practical set of conditions for an additively finitely generated Lie ring L to satisfy an Engel condition. We present a simpler and more direct proof of this fact.

Baltic Region, 2023 As a scientific method, comparative studies respond to the needs of society. However, the logic of globalisation has reduced the demand for comparative analysis in international and national (regional) studies. Nevertheless, old, settled coastal areas —

Identities with Engel conditions on derivations
Monatshefte für Mathematik, 2010 Let \(R\) be a semiprime ring with center \(Z(R)\), symmetric Martindale quotient ring \(Q\), and nonzero derivation \(D\). The authors prove two results involving \(D\) and Engel conditions. Let \([x,y_1]_1=xy_1-y_1x\) and for \(n>1\) set \([x,y_1,\dots,y_n]_n=[[x,y_1,\dots,y_{n-1}]_{n-1},y_n]_1\).

On singularity of distribution of random variables with independent symbols of Oppenheim expansions
Modern Stochastics: Theory and Applications, 2017 The paper is devoted to the restricted Oppenheim expansion of real numbers ($\mathit{ROE}$), which includes already known Engel, Sylvester and Lüroth expansions as partial cases.

Radical Rings with Engel Conditions
Journal of Algebra, 2000 In a ring \(R\) the Lie multiplication and the Lie commutators are defined inductively by \([r,s]=rs-sr\), and \([r_1,\dots,r_{n+1}]=[[r_1,\dots,r_n],r_{n+1}]\). A ring \(R\) is \(n\)-Engel, if \([r,s,\dots,s]=0\) where \(s\) appears exactly \(n\) times.

Engel, Nilpotent and Solvable BCI-algebras
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 In this paper, we define the concepts of Engel, nilpotent and solvable BCI-algebras and investigate some of their properties. Specially, we prove that any BCK-algebra is a 2-Engel.

Quadratic engel curves and consumer demand [PDF]
, 1997 This paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative ...
