Massive gravity, canonical structure and gauge symmetry

Massive gravity, canonical structure and gauge symmetry

Performing Hamiltonian analysis of the massive gravity [9] in full phase space, we see that the theory is ghost free. We also see in a more clear way that this result is intrinsic of the interaction term and does not depend on the variables involved. Since no first class constraint emerges, the theo...
