We discuss the dynamics of three-dimensional Maxwell theory coupled to a level-k Chern-Simons term. Motivated by S-duality in string theory, we argue that the theory admits an S-dual description. The S-dual theory contains a nongauge one-form field, previously proposed by Deser and Jackiw [Phys. Lett. 139B, 371 (1984).PYLBAJ0370-269310.1088/1126-6708/1999/10/036] and a level-k U(1) Chern-Simons term, Z_{MCS}=Z_{DJ}Z_{CS}. The couplings to external electric and magnetic currents and their string theory realizations are also discussed.
我们讨论了三维麦克斯韦理论与层阶 k 陈-西蒙斯项的动力学。受弦论中的 S 对偶性的启发，我们认为该理论存在 S 对偶描述。S 对偶理论包含一个非规范的一形式场，该场由 Deser 和 Jackiw 提出[Phys. Lett. 139B, 371 (1984).PYLBAJ0370-269310.1088/1126-6708/1999/10/036]，以及一个层阶 k U(1) 陈-西蒙斯项，Z_{MCS}=Z_{DJ}Z_{CS}。我们还讨论了对外电场和磁场电流的耦合及其弦论实现。
