DESCRIPTION:Speakers: Kostiantyn Tolmachov (Hamburg)\n\nI will report on t
 wo recent papers establishing some geometric and categorical properties of
  character sheaves. In one\, joint with Gonin and Ionov\, we give a new pr
 oof and an extension to non-unipotent setting of the t-exactness of the co
 mposition of Radon and Harish-Chandra transforms for character sheaves. In
  another\, joint with Bezrukavnikov\, Ionov and Varshavsky\, we show that 
 this can be used to compute the Drinfeld center of the abelian Hecke categ
 ory attached to the same reductive group.\n\nhttps://math-events.uni-bonn.
