Query: Homotopy theory of $C_\infty$-algebras and characteristic classes of
  fiber bundles   In this paper we give a Chern-Weil-type construction of characteristic
classes of fiber bundles, based on homotopy theory of C-infinity algebras. Our
idea is to replace a family of closed manifolds to a family of C-infinity
morphisms with family of metrics.
