Query: A differential topological invariant on spin manifolds from
  supersymmetric path integrals   We show that the N=1/2 supersymmetric path integral on a closed even
dimensional Riemannian spin manifold, realized via Chen forms and recent
results from noncommutative geometry, induces a differential topological
invariant (which does not depend on the Riemannian metric).
