Non-Abelian gauge theories invariant under diffeomorphisms

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