DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CHAT/3/">Gal
 ois representations and torsion cohomology: a series of misunderstandings<
 /a>\nby Michael Harris (Columbia) as part of CHAT (Career\, History And Th
 oughts) series\n\n\nAbstract\nIn 2013\, Peter Scholze announced his proof 
 that Galois representations with finite coefficients could be associated t
 o \ntorsion classes in the cohomology of certain locally symmetric spaces.
   The existence of such a\ncorrespondence had been predicted by a number o
 f mathematicians but for a long time no one had the slightest idea\nhow to
  construct the Galois representations.  In this talk I will review some of
  the history of the problem\, with\nemphasis on the many false starts and 
 occasional successes\, and on my own intermittent involvement\nwith this a
 nd related problems.\n
