Speaker: Ryszard Nest (University of Copenhagen)
Host: Huaxin Lin
Abstract: We will review the triangulated structure of the “decorated” KK-category, associated applications of homological algebra and examples including Baum-Connes conjecture for locally compact groups, compact quantum groups and to some closure properties of the UCT category.
Time: 16:00-17:00 pm, Thursday, April 17
Location: Room 1410, SIMIS
