Our results apply in particular to classes on GSpin Shimura varieties associat ed with arbitrary positive semi-definite symmetric matrices\, as well as t o certain unitary and quaternionic Shimura varieties. We show that these c lasses agree with the ones constructed in work with B. Howard using $K$-th eoretic methods.\n LOCATION:https://researchseminars.org/talk/MITNT/43/ END:VEVENT END:VCALENDAR
