Invariable generation and wreath products

Abstract

Invariable generation is a topic that has predominantly been studied for finite groups. In 2014, Kantor, Lubotzky, and Shalev produced extensive tools for investigating invariable generation for infinite groups. Since their paper, various authors have investigated the property for particular infinite groups or families of infinite groups. A group is invariably generated by a subset SS if replacing each element of SS with any of its conjugates still results in a generating set for GG. In this paper we investigate how this property behaves with respect to wreath products. Our main work is to deal with the case where the base of GXHG\wr_X H is not invariably generated. We see both positive and negative results here depending on HH and its action on XX.
