 ">Motives in Geometric Representation Theory II</a>\nby Jens Eberhardt (Un
 iversity of Wuppertal) as part of Algebra and Geometry Seminar @ HKUST\n\n
 Lecture held in Room 2503.\n\nAbstract\nRecent constructions in motivic ho
 motopy theory offer exciting new applications in geometric representation 
 theory. For example\, they allow to consider mixed perverse sheaves (a gra
 ded version of perverse sheaves) with integral coefficients or K-motives (
 a K-theoretic analogue of constructible sheaves).\n\nIn this lecture serie
 s\, we will explain how to work with motives in practice. We focus on moti
 vic cohomology\, the motivic six functor formalism\, Tate motives\, and we
 ight structures. We will then explain the notion of stratified mixed Tate 
 motives which\, when specialized to (affine/partial) flag varieties\, yiel
 ds a geometric perspective on Koszul duality. Lastly\, we will introduce r
 esults and conjectures relating K-motives and the geometric Langlands prog
 ram.\n
