摘要
We examine the issue of duality both in electrodynamics and in Kalb-Ramond scalar axion systems. In D space-time dimensions the dual abelian theories of (p - 1)- and (D - p - 1)-form potentials have vacua classified by the dimensions of the cohomology spaces H(p-1)((D-1)M) or H(D-p-1)((D-1)M), respectively. The vacua are characterized by topological charges which are expectation values for generalized ''Wilson loop'' operators around non-trivial cycles. In certain instances the vacua exhibit a theta angle parametrization much as in QCD. The relation of axionic hair and discrete gauge hair is analyzed in the topologically massive Kalb-Ramond theory. If there are no fundamental strings in the theory, axionic charge is replaced by an irrelevant vacuum angle.
