SUMMARY:Sucharit Sarkar: \"Constructing CW complexes from grid diagrams\
 "
DESCRIPTION:Abstract: Given a knot presented in a grid diagram\, we cons
 truct a CW complex which has one cell for each generator of the grid cha
 in complex and whose attaching maps correspond to the chain complex boun
 dary map. Thus the homology of this space is the knot Floer homology. We
  will show that the stable homotopy type of this CW complex is actually 
 a knot invariant.
