DESCRIPTION:Title: On the automorphism group of cyclic products of groups.
 \n\nGraph products of groups are a construction that interpolates between 
 direct products and free products\, and contain well-known examples such a
 s right-angled Coxeter groups and right-angled Artin groups. In this talk\
 , I will present a form of rigidity for the automorphism group of `cyclic 
 products of groups'\, that is\, the graph products over cycles on at least
  5 vertices. I will recall a construction due to Davis that allows us to u
 nderstand graph products through their action on CAT(0) cube complexes\, a
 nd explain how this action extends to the whole automorphism group in the 
 case of cyclic products of at least 5 groups. Such an action can be used t
 o completely compute their automorphism group and to show their acylindric
 al hyperbolicity. This is joint work with Anthony Genevois.\n
