Non-abelian self-duality from self-interaction
The non-abelian self-dual action in three dimensions is derived using the self-interaction mechanism. Self-duality in three dimensions was proposed initially by Townsend et. al. [1] as an alternative to the topologically massive theory[2]. In principle, they seem different descriptions of a locally massive spin 1 physical excitation: the self-dual theory is described by a non-gauge invariant fi...
متن کاملActions for Non-Abelian Twisted Self-Duality
The dynamics of abelian vector and antisymmetric tensor gauge fields can be described in terms of twisted self-duality equations. These first-order equations relate the p-form fields to their dual forms by demanding that their respective field strengths are dual to each other. It is well known that such equations can be integrated to a local action that carries on equal footing the p-forms toge...
متن کاملSelf-duality and parity in non-abelian Lubin–Tate theory
We give a geometric proof of a “parity-switching” phenomenon that occurs when applying the local Langlands and Jacquet–Langlands correspondence to a self-dual supercuspidal representation ofGL(n) over a nonarchimedean local field. This turns out to reflect a duality property on the self-dual part of the `-adic étale cohomology of the Lubin–Tate tower.
متن کاملAction Principle for Non-Abelian Twisted Self-Duality
The dynamics of abelian vector and antisymmetric tensor gauge fields can be described in terms of twisted self-duality equations. The latter play an important role in exposing the duality symmetries of the theory. I this contribution I review recent progress in the construction of action principles for these equations and in particular their non-abelian generalizations.
متن کاملOn Non-Abelian Duality
A general study of non-abelian duality is presented. We first identify a possible obstruction to the conformal invariance of the dual theory for non-semisimple groups. We construct the exact non-abelian dual for any Wess-Zumino-Witten (WZW) model for any anomaly free subgroup, and the corresponding extension for coset conformal field theories. We characterize the exact non-abelian dual for σ-mo...
