Description
Gauge p-forms in diverse dimensions naturally occur in supergravity and string theory. This talk will review new formulations for interacting gauge p-form theories in d = 2p + 2 space-time dimensions. For odd p, such theories possess U(1) duality invariance and include the Born-Infeld action as a well-known representative. For even p, each theory describes a self-interacting chiral boson with a self-dual field strength. In the four-dimensional case, an important example is a low-energy effective action for the N = 4 supersymmetric Yang-Mills theory on its Coulomb branch where the gauge group SU(n) is spontaneously broken to SU(n-1) x U(1) and the dynamics is described by a single N = 2 this effective action will be briefly discussed.
