DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LNTS/111/">O
 n Exotic Hecke correspondences</a>\nby Pol van Hoften (VU Amsterdam) as pa
 rt of London number theory seminar\n\nLecture held in Room 140\, the Huxle
 y Building\, Imperial College London.\n\nAbstract\nThe goal of this talk i
 s to explain joint work in progress with Jack Sempliner on the constructio
 n of "exotic" Hecke correspondences between the mod p fibers of different 
 Shimura varieties of Hodge type. Our work generalizes forthcoming work of 
 Xiao-Zhu\; our results cover the new situation where the groups underlying
  the two different Shimura varieties are allowed to be to be non-isomorphi
 c at p. As a consequence of our main results\, we obtain exotic isomorphis
 ms of Igusa varieties in the style of Caraiani-Tamiozzo. In the talk\, I w
 ill give many illustrative examples.\n
