DESCRIPTION:Henry Cohn (Microsoft Research and MIT)\nSome exceptional stru
 ctures such as the icosahedron or E_8 root system have remarkable optimali
 ty properties in settings such as packing\, energy minimization\, or codin
 g.  How can we understand and prove their optimality?  In this talk\, I'
 ll interweave this story with two other developments in recent mathematics
  (without assuming familiarity with either): how semidefinite optimization
  and sums of squares have expanded the scope of optimization\, and how rep
 resentation theory has shed light on higher correlation functions for part
 icle systems.
