DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WSIPM/5/">Re
 construction of groupoids\, and classification of Fell algebras</a>\nby Ai
 dan Sims as part of Western Sydney\, IPM joint workshop on Operator Algebr
 as\n\n\nAbstract\nI will the history of reconstruction of groupoids from p
 airs of operator algebras\, from Feldman and Moore’s results on von Neum
 ann algebras through Kumjian’s and then Renault’s results about C*-alg
 ebras of twists\, and including some recent results about groupoids that a
 re not topologically principal. I will finish by outlining how Kumjian’s
  theory leads to a Dixmier-Douady classification theorem for Fell algebras
