Description

Given a finite graph $\Gamma$ with vertices labelled by groups $G_1, \dots, G_n$, the graph product is a neat construction that interpolates between the free product $G_1 \ast G_2 \ast \cdots \ast G_n$ and the direct product $G_1 \times G_2 \times \cdots \times G_n$.  Right-angled Coxeter groups and right-angled Artin groups are well-studied examples of groups naturally represented as graph products of groups. The automorphism groups of graph products of groups are interesting for their relationships to other well-studied groups of automorphisms, and for the things that remain unknown about them.  We give an overview of some results.

In person attendance is available in HN 1.33 for up to 52 people.

All attendees will be asked to check in using the CBR Covid-safe Check-In app or sign in on arrival.
