Actions for Non-Abelian Twisted Self-Duality

Thursday 30 June 2011 14:00 -  Tours -  Salle 1180 (Bât E2)

Résumé :
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 talk I discuss recent progress in the construction of action principles for these equations and in particular for their non-abelian generalizations. I discuss possible applications (to Yang-Mills and supergravity theories) and comment on the relation to previous no-go theorems.
