Abstract
We construct a central extension of the smooth Deligne cohomology group of a compact oriented odd dimensional smooth manifold, generalizing that of the loop group of the circle. While the central extension turns out to be trivial for a manifold of dimension 3, 7, 11,..., it is non-trivial for 1, 5, 9,.... In the case where the central extension is non-trivial, we show an analogue of the Segal-Witten reciprocity law.
