SUMMARY:Arcs as an effective model - Kaufmann\, R (Purdue University)

DESCRIPTION:The arc operad and its variations have proven itself in many i
 nstances to be a very clean minimal and explicit tool\; for instance in gi
 ving models for the little discs\, framed little discs\, E_n operads\, Sul
 livan PROP\, etc on the topological level by basically the same formalism 
 on surface. Furthermore\, these models have a very nice cellular structure
  and hence are naturally suited to solve chain level conjectures. We will 
 present some of these constructions and draw parallels to other activities
  at the program.\n\n
