Title: "Hamiltonian analysis of BHT massive gravity
"
Abstract:
We study the Hamiltonian structure of the Bergshoeff-Hohm-Townsend
(BHT) massive gravity with a cosmological constant. In the space of
coupling constants $(\Lambda_0,m2)$, our canonical analysis reveals the
special role of the condition $\Lambda_0/m2\ne-1$. In this sector, the
dimension of the physical phase space is found to be $N^*=4$, which
corresponds to two Lagrangian degree of freedom. When applied to the
AdS asymptotic region, the canonical approach yields the conserved
charges of the BTZ black hole, and central charges of the asymptotic
symmetry algebra.
