 ">Motives in Geometric Representation Theory V</a>\nby Jens Eberhardt (Uni
 versity of Wuppertal) as part of Algebra and Geometry Seminar @ HKUST\n\nL
 ecture held in Room 5510.\n\nAbstract\nRecent constructions in motivic hom
 otopy theory offer exciting new applications in geometric representation t
 heory. For example\, they allow to consider mixed perverse sheaves (a grad
 ed version of perverse sheaves) with integral coefficients or K-motives (a
  K-theoretic analogue of constructible sheaves).\n\nIn this lecture series
 \, we will explain how to work with motives in practice. We focus on motiv
 ic cohomology\, the motivic six functor formalism\, Tate motives\, and wei
 ght structures. We will then explain the notion of stratified mixed Tate m
 otives which\, when specialized to (affine/partial) flag varieties\, yield
 s a geometric perspective on Koszul duality. Lastly\, we will introduce re
 sults and conjectures relating K-motives and the geometric Langlands progr
 am.\n
