A Class of Rearrangement Groups that are not Invariably Generated

Group Theory 2024-04-29 v3

Abstract

A group GG is invariably generated if there exists a subset SGS \subseteq G such that, for every choice gsGg_s \in G for sSs \in S, the group GG is generated by {sgssS}\{ s^{g_s} \mid s \in S \}. In [GGJ16] Gelander, Golan and Juschenko showed that Thompson groups TT and VV are not invariably generated. Here we generalize this result to the larger setting of rearrangement groups, proving that any subgroup of a rearrangement group that has a certain transitive property is not invariably generated.
