Abstract
In this paper we give a sheaf theory interpretation of the twisted cohomology of manifolds. To this end we develop a sheaf theory on smooth stacks. The derived push-forward of the constant sheaf with value along the structure map of a gerbe over a smooth manifold is an object of the derived category of sheaves on . Our main result shows that it is isomorphic in this derived category to a sheaf of twisted de Rham complexes.
