Hamiltonian analysis of symmetries in a massive theory of gravity
arXiv:1108.4591 · doi:10.1007/JHEP10(2011)121
Abstract
We construct the generator of hamiltonian gauge symmetries in a 2+1 dimensional massive theory of gravity, proposed recently, through a systematic off-shell algorithm. Using a field dependant map among gauge parameters we show that the symmetries obtained from this generator are on-shell equivalent to the Poincaré gauge symmetries. We also clarify certain subtle issues concerning the implementation of this map.
