A Note on π-Engel Conditions

Southeast Asian Bulletin of Mathematics, 2001
For a set of primes \(\pi\), the concept of Engel conditions for finite groups is extended. For example an element \(g\) is a weakly right \(\pi\)-Engel element if for each \(\pi'\)-element \(x\) in the group \(G\) there is a positive integer \(n\) such that the \((n+1)\)-commutator \([x,g,\dots,g]\) is a \(\pi\)-element.

RINGS SATISFYING GENERALIZED ENGEL CONDITIONS

Journal of Algebra and Its Applications, 2012
Let R be an associative ring and let x, y ∈ R. Define the generalized commutators as follows: [x, 0y] = x and [x, ky] = [x, k-1y]y - y[x, k-1y](k = 1, 2, …). In this paper we study some generalized Engel rings, i.e. [Formula: see text]-rings (satisfying [xm(x, y), k(x, y)y] = 0), [Formula: see text]-rings (satisfying [xm(x, y), k(x, y)yn(x, y)] = 0 ...

Skew derivations with annihilating Engel conditions

Publicationes Mathematicae Debrecen, 2006
Let \(R\) be a noncommutative prime ring. Let \(\sigma\) be an automorphism of \(R\), \(\delta\) be a \(\sigma\)-derivation, and \(a\in R\). The authors prove that if \(a[\delta(x),x]_k=0\) for any \(x\in R\), where \(k\) is a fixed positive integer, then either \(a=0\) or \(\delta=0\), except when \(R=M_2(\text{GF}(2))\).

An Engel condition with skew derivations

Monatshefte für Mathematik, 2008
The authors extend [\textit{C. Lanski}, Proc. Am. Math. Soc. 118, No. 3, 731-734 (1993; Zbl 0821.16037)] from derivations to skew derivations. Let \(R\) be a prime ring and \(L\) a noncommutative Lie ideal of \(R\). For \(x,y\in R\) set \([x,y]_1=[x,y]=xy-yx\) and when \(n>1\) let \([x,y]_n=[[x,y]_{n-1},y]\).

ON n-ENGEL PAIR SATISFYING CERTAIN CONDITIONS

Journal of Algebra and Its Applications, 2014
Let G be a group and h, g ∈ G. The 2-tuple (h, g) is said to be an n-Engel pair, n ≥ 2, if h = [h,n g], g = [g,n h] and h ≠ 1. In this paper, we prove that if (h, g) is an n-Engel pair, hgh-2gh = ghg and ghg-2hg = hgh, then n = 2k where k = 4 or k ≥ 6. Furthermore, the subgroup generated by {h, g} is determined for k = 4, 6, 7 and 8.

Semilocal rings with Engel conditions

Archiv der Mathematik, 2006
The relation between the Engel structure of a semilocal ring and that of its multiplicative group is investigated. Suppose that every local ring whose multiplicative group satisfies an m-Engel condition for some positive integer m is an f (m)-Engel ring for some function f .

Skew Derivations and Engel Conditions

Communications in Algebra, 2013
It is known that for a nonzero derivation d of a prime ring R, if a nonzero ideal I of R satisfies the Engel-type identity [[…[[d(x k 0 ), x k 1 ], x k 2 ],…], x k n ], then R is commutative. Here we extend this result to a skew derivation of R for a Lie ideal I, which has an immediate corollary that replaces d by an automorphism of R. A related result

Involution Satisfying an Engel Condition

Communications in Algebra, 2016
We are given a semiprime ring R with involution *. We show that the following conditions are equivalent. Condition 1: For each element x of R, [x*, x](=x*x − xx*) = 0. Condition 2: There is a fixed natural number N′ such that [x*, xN′] = 0, all elements x of R. Condition 3: There is a fixed natural number N such that for each element x of R, , where dx
