A fiber integration formula for the smooth Deligne cohomology
As is well known, an important operation exists in de Rham cohomology called integration along the fiber for a fiber bundle. In this paper, we extend it to the smooth Deligne cohomology, which is a refinement of ordinary cohomology. First we construct such an explicit map on the
ech cochains and prove a Stokes-type formula which shows that it is a chain map when the fiber has no boundary. Second we prove that the induced map on the smooth Deligne cohomology is canonical; that is, it is independent of all choices used in the construction.
