DESCRIPTION:Graph products of groups generalise both right-angled Coxeter 
 groups and  right-angled Artin groups. While such groups are already known
  to act  on right-angled buildings\, I will explain how it is possible\, w
 hen 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 geome
 try.  (joint work with A. Genevois)<br>
