“…Another interesting aspect of TMG is the existence of warped AdS black hole solutions. These solutions with central charge expressions were a starting point for the warped AdS/CFT correspondence [36] and the Kerr/CFT correspondence [37], which may be extended to the dS/CFT case [38,39,40].…”

We extend our recent work on the quasilocal formulation of conserved charges to a theory of gravity containing a gravitational Chern-Simons term. As an application of our formulation, we compute the off-shell potential and quasilocal conserved charges of some black holes in threedimensional topologically massive gravity. Our formulation for conserved charges reproduces very effectively the well-known expressions on conserved charges and the entropy expression of black holes in the topologically massive gravity. *

We study the asymptotically flat rotating hairy black hole solution of a three-dimensional gravity theory which is given by taking the flat-space limit (zero cosmological constant limit) of new massive gravity. We propose that the dual field theory of the flat-space limit of new massive gravity can be described by a contracted conformal field theory which is invariant under the action of the BMS 3 group. Using the flat/ contracted conformal field theory correspondence, we construct a stress tensor which yields the conserved charges of the asymptotically flat black hole solution. We check that our expressions of the mass and angular momentum fit with the first law of black hole thermodynamics. Furthermore, by taking the appropriate limit of the Cardy formula in the parent conformal field theory, we find a Cardy-like formula which reproduces the Wald's entropy of the 3D asymptotically flat black hole.

“…One goal of this paper is to discuss the question of cosmological singularities in general and big-bang singularity in particular in the context of higher-spin gravity. We focus on a precise formulation of the problem and do not address potentially related questions such as the dS/CFT correspondence, see [44,45] for a discussion of those topics. There is already a very rich history of resolutions of cosmological singularities in string theory, see for example: [46,47,48,49] and the review [50] for more references; more recent works include also [51,52,53].…”

We study the resolution of certain cosmological singularity in the context of higherspin three-dimensional gravity. We consider gravity coupled to a spin-3 field realized as Chern-Simons theory with gauge group SL(3, C). In this context we elaborate and extend a singularity resolution scheme proposed by Krishnan and Roy. We discuss the resolution of a big-bang singularity in the case of gravity coupled to a spin-4 field realized as Chern-Simons theory with gauge group SL(4, C). In all these cases we show the existence of gauge transformations that do not change the holonomy of the Chern-Simons gauge potential and lead to metrics without the initial singularity. We argue that such transformations always exist in the context of gravity coupled to a spin-N field when described by Chern-Simons with gauge group SL(N, C). Three-dimensional higher spin gravity as a Chern-Simons theoryLet us first review how in three dimensions Einstein gravity can be written in terms of Chern-Simons theory [54] [55]. In particular, we shall review how dS 3 appears as a solution of Chern-Simons with SL(2, C) gauge group. On the Chern-Simons side the starting point is a pair of connections taking values in the algebra sl(2) with generators {L 0 , L 1 , L −1 } (see appendix (A) for an explicit realization of the generators).
