Event details
Graph products of groups are a construction that interpolates between direct products and free products, and contain well-known examples such as right-angled Coxeter groups and right-angled Artin groups. I will give an overview of some results regarding their automorphism groups. I will also explain a construction due to Davis that allows us to understand graph products through their action on CAT(0) cube complexes. Such an action can be used to completely compute their automorphism groups in certain cases, and to reveal certain hyperbolic-like features of their automorphism groups. This is joint work with Anthony Genevois.
