DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BRAG/5/">Abo
 ut the McKay correspondence in 3 dimensions</a>\nby Ugo Bruzzo (SISSA/UFPB
 ) as part of Brazilian algebraic geometry seminar\n\n\nAbstract\nAbstract:
  I will review work on the McKay correspondence in 3 dimensions and its di
 fferential-geometric version\, relying on papers by Ito-Reid\, Sardo Infir
 ri\, Craw-Ishi and others\, and on some original results obtained with a g
 roup of collaborators. This is about the resolution of singularities of th
 e type C^3/G\, where G is a finite subgroup of GL(3\,C) or SL(3\,C). I wil
 l also discuss the chamber structure for the stability parameter of the GI
 T quotient. I will illustrate the general theory by means of a nontrivial 
 but manageable example (C^3/Z_4 with Z_4 acting as a subrgoup of SL(3\,C))
 . I will also hint at some physical motivations.\n\nLink for the Zoom meet
