Title: "On the small cancellation geometry of certain graph products of groups."
Speaker: Alexandre Martin (Universitšt Wien)
Abstract: Graph products of groups generalise both right-angled Coxeter groups and right-angled Artin groups. While such groups are already known to act on buildings, I will explain how it is possible, when the underlying graph is a cycle, to construct a more "robust" action on a small cancellation polygonal complex. Such an action can be used to compute the automorphism group of such groups and understand their geometry. (joint work with A. Genevois)
