Profinite groups with an automorphism whose fixed points are right Engel

Group Theory 2018-08-15 v1

Abstract

An element gg of a group GG is said to be right Engel if for every xGx\in G there is a number n=n(g,x)n=n(g,x) such that [g,nx]=1[g,{}_{n}x]=1. We prove that if a profinite group GG admits a coprime automorphism φ\varphi of prime order such that every fixed point of φ\varphi is a right Engel element, then GG is locally nilpotent.
