SUMMARY:Graph-complexes: from finite type knot invariants in R^3 to the ra

DESCRIPTION:I will start by explaining how graph-complexes (or rather grap
 h-spaces) appear in the study of Vassiliev invariants (also called finite 
 type invariants) of the usual knots and links in R^3. I will then talk abo
 ut Haefliger's computations of isotopy classes of higher dimensional links
  and then about the rational homotopy type of embedding spaces with target
  the Euclidean space. At some point I will also speak about the spaces of 
 long embeddings and how they are related to the deformation theory of the 
 little discs operads.
