Then we explain how to\ncompute these groups and the homotopy type of the spectru m using recent\nwork on K-theory and L-theory. If time permits we also exp lain how to\nresolve the homotopy limit problem for rings of integers in n umber\nfields and prove Karoubi's periodicity conjecure for arbitrary ring s.\n LOCATION:https://researchseminars.org/talk/eAKTS/14/ END:VEVENT END:VCALENDAR
