DESCRIPTION:Speaker: David Hernandez\nhosted by Xujia Chen & Tamas Hausel\n
 Abstract: Shifted quantum groups emerged from the study of quantized Coulo
 mb branches (which are symplectic duals to quiver varieties). We show that
  the Grothendieck ring of the category O for the shifted quantum affine al
 gebras has the structure of a cluster algebra (jt work with Geiss and Lecl
 erc). This has several applications\, such as geometric character formulas
  for simple classes corresponding to cluster variables.
