Query: Categorified quantum sl(2) and equivariant cohomology of iterated flag
  varieties   A 2-category was introduced in arXiv:0803.3652 [math.QA] that categorifies
Lusztig's integral version of quantum sl(2). Here we construct for each
positive integer N arepresentation of this 2-category using the equivariant
cohomology of iterated flag varieties. This representation categorifies the
irreducible (N+1)-dimensional representation of quantum sl(2).
