DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/66/
 ">Nilpotent orbits for classical groups</a>\nby Hiraku Nakajima (Kavli Ins
 titute for the Physics and Mathematics of the Universe) as part of Algebra
  and Geometry Seminar @ HKUST\n\nLecture held in Room 4475 (Lifts 25/26).\
 n\nAbstract\nKraft-Procesi realized nilpotent orbits for classical groups 
 as orthosymplectic quiver varieties\, which are defined as quiver varietie
 s\, but replacing products of GL by products of O and Sp. Motivated by stu
 dy of Coulomb branches\, we introduce variants of these\, which remove `ba
 d' behavior of nilpotent orbit closures\, such as non-irreducibility\, non
 -normality\, etc. This talk is based on on-going project with Finkelberg a
 nd Hanany.\n
