Generalized abelian S-duality and coset constructions Original Research Article

Electric-magnetic duality and higher dimensional analogs are obtained as symmetries in generalized coset constructions, similar to the axial-vector duality of two-dimensional coset models described by Roček and Verlinde. We also study global aspects of duality between p-forms and (d — p — 2)-forms in d-manifolds. In particular, the modular duality anomaly is governed by the Euler character as in four and two dimensions. Duality transformations of Wilson line operator insertions are also considered.
