DESCRIPTION:I will describe a simple "combinatorial" object\, Kontsevich's
  graph complex GC_d\, with the necessary background to understand the defi
 nition\, and then explain some elementary calculations with it. I will the
 n explain how it plays a role in a conjectural picture of the topology of 
 the space of all homeomorphisms of R^d^\, as well as the space of all diff
 eomorphisms of D^d^.
