 TLE: Galois symmetries of the stable homology of integer symplectic groups.
 \n\nABSTRACT: There are many natural sequences of moduli spaces in algebrai
 c geometry whose homology approaches a "limit"\, despite the fact that the 
 spaces themselves have growing dimension.  If these moduli spaces are defin
 ed over a field K\,  this limiting homology carries an extra structure -- a
 n action of the Galois group of K --  which is arithmetically interesting.\
 n\nIn joint work with Feng and Galatius\, we compute this action (or rather
  a slight variant) in the case of the moduli space of abelian varieties. I 
 will explain the answer and why I find it interesting. No familiarity with 
 abelian varieties will be assumed -- I will emphasize topology over algebra
 ic geometry.\n\n___________________________\n\nPlease join us by clicking t
