DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGNTISTA/32/
 ">Affine Grassmannian slices and their quantizations</a>\nby Joel Kamnitze
 r (University of Toronto) as part of Algebraic Geometry and Number Theory 
 seminar - ISTA\n\n\nAbstract\nSlices in the affine Grassmannian are geomet
 ric incarnations of weight spaces of representations of semisimple complex
  groups.  These spaces can also be constructed as Coulomb branches of quiv
 er gauge theories or in type A\, as bow varieties.  They are related to Na
 kajima quiver varieties using 3d mirror symmetry\, also known as symplecti
 c duality.   These spaces are conical symplectic singularities and have na
 tural quantizations using algebras called truncated shifted Yangians.  I w
 ill survey 10 years of research on these wonderful spaces and describe som
 e remaining open questions.\n
