DESCRIPTION:Gabor Elek (Lancaster)\nRecently\, I defined a notion of limit
  for finite Schreier graphs. It turns out that the natural limit objects a
 re stable continuous group actions on the Cantor set. The limit notion lea
 ds to the definition of qualitative weak equivalence (this notion has alre
 ady been defined by Matui and Li for minimal actions of the integers). I w
 ill show some results on the space of weak equivalence classes and will al
 lude to some applications in the theory of local distributed algorithms.
