Massive gravity in three dimensions.
A particular higher-derivative extension of the Einstein-Hilbert action in three spacetime dimensions is shown to be equivalent at the linearized level to the (unitary) Pauli-Fierz action for a massive spin-2 field. A more general model, which also includes "topologically-massive" gravity as a special case, propagates the two spin-2 helicity states with different masses. We discuss the extensio...
متن کاملBigravity and Lorentz-violating Massive Gravity
Bigravity is a natural arena where a non-linear theory of massive gravity can be formulated. If the interaction between the metrics f and g is non-derivative, spherically symmetric exact solutions can be found. At large distances from the origin, these are generically Lorentz-breaking bi-flat solutions (provided that the corresponding vacuum energies are adjusted appropriately). The spectrum of...
متن کاملBigravity as a Tool for Massive Gravity
The formulation of massive gravity as bigravity is discussed. We argue that bigravity is more than a tool to tackle massive deformation of gravity.
متن کاملRenormalizability of Massive Gravity in Three Dimensions
We discuss renormalizability of a recently established, massive gravity theory with particular higher derivative terms in three space-time dimensions. It is shown that this massive gravity is certainly renormalizable as well as unitary, so it gives us a physically interesting toy model of perturbative quantum gravity in three dimensions.

متن کاملChiral Gravity in Three Dimensions
Three dimensional Einstein gravity with negative cosmological constant −1/l2 deformed by a gravitational Chern-Simons action with coefficient 1/μ is studied in an asymptotically AdS3 spacetime. It is argued to violate unitary or positivity for generic μ due to negativeenergy massive gravitons. However at the critical value μl = 1, the massive gravitons disappear and BTZ black holes all have mas...
