三明治群与群中的(强)左3-Engel元

Sandwich groups and (strong) left 3-Engel elements in groups

Anastasia Hadjievangelou, Gunnar Traustason

摘要:

本文证明了Kostrikin和Zel'manov关于三明治李代数的局部零解定理的一个群论类似定理。引入群G的强左3-Engel元的概念,并证明它们总是在群G的局部幂零根中.这推广了Jabara和Traustason以前的一个结果,该结果表明群G的左3-Engel元a在G的局部幂零根中,只要a是奇数阶。

英文摘要:

In this paper we prove a group theoretic analogue of the well known local nilpotence theorem for sandwich Lie algebras due to Kostrikin and Zel'manov. We introduce the notion of a strong left 3-Engel element of a group G and show that these are always in the locally nilpotent radical of G. This generalises a previous result of Jabara and Traustason that showed that a left 3-Engel element a of a group G is in the locally nilpotent radical of G whenever a is of odd order.
