DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GRT-2020/5/"
 >K-Motives and Koszul Duality</a>\nby Jens Eberhardt (MPIM Bonn) as part o
 f Geometric Representation Theory conference\n\n\nAbstract\nKoszul duality
 \, as conceived by Beilinson-Ginzburg-Soergel\, describes a remarkable sym
 metry in the representation theory of Langlands dual reductive groups. Geo
 metrically\, Koszul duality can be stated as an equivalence of categories 
 of mixed (motivic) sheaves on flag varieties. In this talk\, I will argue 
 that there should be an an 'ungraded' version of Koszul duality between mo
 nodromic constructible sheaves and equivariant $K$-motives on flag varieti
 es. For this\, I will explain what $K$-motives are and present preliminary
  results.\n
