DESCRIPTION:Speaker: Mikhail Shkolnikov\nhosted by Herbert Edelsbrunner\nAb
 stract: Title: Limit of the sandpile groupThe sandpile group is a finite a
 belian group defined for any graph. It is ofspecial interest for the piece
  of the lattice bounded by some convex domain. There arestrong indications
  that there is a limit for these groups when one fixes the domain andsends
  the mesh of the lattice to zero. Until recently\, nobody was able tomake 
 rigorous sense of this vague statement. Here is what we are suggesting: 1)
  for a given mesh\, define a visual-type heuristic metric on the sandpile\
 ; 2) look at the persistence diagrams and whether they stabilise when mesh
  vanishes.
