Invariable generation of Thompson groups

Abstract

A subset SS of a group GG invariably generates GG if G=sg(s)sSG= \langle s^{g(s)} | s \in S\rangle for every choice of g(s)G,sSg(s) \in G,s \in S. We say that a group GG is invariably generated if such SS exists, or equivalently if S=GS=G invariably generates GG. In this paper, we study invariable generation of Thompson groups. We show that Thompson group FF is invariable generated by a finite set, whereas Thompson groups TT and VV are not invariable generated.
