DESCRIPTION:Zhouli Xu\, MIT\n\nTitle: “Smooth structures\, stable homotop
 y groups of spheres and motivic homotopy theory”\n\nAbstract: Following 
 Kervaire-Milnor\, Browder and Hill-Hopkins-Ravenel\, Guozhen Wang and I sh
 owed that the 61-sphere has a unique smooth structure and is the last odd 
 dimensional case: $S^1\, S^3\, S^5$ and $S^{61}$ are the only odd dimensio
 nal spheres with a unique smooth structure. The proof is a computation of 
 stable homotopy groups of spheres. We introduce a method that computes dif
 ferentials in the Adams spectral sequence by comparing with differentials 
 in the Atiyah-Hirzebruch spectral sequence for real projective spectra thr
 ough Kahn-Priddy theorem. I will also discuss recent progress of computing
  stable stems using motivic homotopy theory with Dan Isaksen and Guozhen W
 ang.
