On Wednesday the 10th of November 2021, Charles Cox (University of Bristol) will be giving an online seminar on his research at 3pm. The details of his talk are as follows:

Title: What is a wreath product, and how does invariable generation behave with respect to it?

Abstract: The direct product is probably the easiest way to take two groups G and H and define a new one G x H. A wreath product, G wr H, is another way. We’ll begin with a gentle introduction wreath products, and I will try to work only with concrete examples (all infinite groups based in some way on the integers). We’ll then see the notion of a group having an invariable generating set. There are then two proofs that I’ve written recently, whose basic ideas I’ll hopefully capture for an audience new to the definitions being introduced. I hope to illustrate where the proofs have come from and why they are natural.
