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 DTSTART:20180509T190000Z DTEND:20180509T200000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Alexandre Martin (Heriot-Watt University) URL:/mathstat/channels/event/alexandre-martin-heriot-w att-university-287059 END:VEVENT END:VCALENDAR
