Title:  Non-Abelian gauge theories invariant under diffeomorphisms

Olivera Miskovic (Pontificia Universidad Católica de Valparaíso, Chili)

 

Abstract: 

Motivated by the fact that some interesting non-Abelian models invariant under general coordinate transformations do not have a suitable action description yet, we develop a canonical construction of this type of actions in three-dimensional spacetime. As a result, we find a class of theories possessing a finite number of local degrees of freedom. We analyze in detail three particular cases.
