We construct a simply-connecte d non-positively curved space with an action of Tame(k^3). That leads to t he classification of finite subgroups of Tame(k^3). This is joint work wit h Stéphane Lamy.\n DTSTART:20180228T200000Z DTEND:20180228T210000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Piotr Przytycki\, 91ºÚÁÏÍø URL:/mathstat/channels/event/piotr-przytycki-mcgill-un iversity-285299 END:VEVENT END:VCALENDAR
