Causality in 3D massive gravity theories

We study the constraints coming from the local causality requirement in various 2+1 dimensional dynamical theories of gravity. In topologically massive gravity, with a single parity noninvariant massive degree of freedom, and in new massive gravity, with two massive spin-2 degrees of freedom, causal...
