| dc.description | The coupling problem of higher spin fields with a non dynamical background is revisited, focussing our attention in 2+1 dimensional space-time. Starting with a suitable Lagrangian field formulation, we study causality and the conservation of local degrees of freedom in a theory with gravitational (no dynamical) interaction, verifying that this type of theories must be consistent only in some space-time (i.e., dS/AdS). On the other hand, we consider the gravitational field as a dynamical object coupled with material fields as sources, from the point of view of a Yang-Mills gauge formulation for gravity. There we found some constraints on the shape of material fields and we show that introduction of auxiliary fields coupled with gauge connection does eliminate those constraints. The model of a Yang-Mills gauge formulation for topological massive gravity with cosmological constant is briefly introduced and we show that its field equations are consistent with the well known cosmologically extended topological massive gravity of Deser at the torsionless limit. | |
