DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITNT/67/">O
 n the plectic conjecture</a>\nby Daniel Li-Huerta (Harvard University) as 
 part of MIT number theory seminar\n\nLecture held in Room 2-449 in the Sim
 ons Building (building 2).\n\nAbstract\nNekovář–Scholl observed that t
 he étale cohomology groups of Hilbert modular varieties enjoy the action 
 of a much larger profinite group than the absolute Galois group of $\\math
 bb{Q}$: the <i>plectic Galois group</i>. They conjectured that this action
  extends to the level of complexes\, which would give a construction of ca
 nonical classes in higher wedge powers of Selmer groups. I'll explain how 
 this works\, as well as discuss analogues over local fields and global fun
 ction fields.\n
