Canonical structure of BHT massive gravity in warped AdS3 sector
We investigate the asymptotic structure of the three dimensional warped anti
de sitter black holes in the Bergshoeff, Hohm and Townsend massive gravity
using the canonical Hamiltonian formalism. We define the canonical asymptotic
guage generators, which produce the conserved charges and the asymptotic
symmetry group for the warped anti de sitter black holes. The attained symmetry
group is described by a semi direct sum of a Virasoro and a KacMoody algebra.
Using the Sugawara construction, we obtain a direct sum of two Virasoro
algebras. We show that not only the asymptotic conserved charges satisfy the
first law of black hole thermodynamics, but also they lead to the expected
Smarr formula for the warped anti de sitter black holes. We also show that the
black hole entropy obeys the Cardy formula of the dual conformal field theory .Comment: 13 page
Black Holes in Born-Infeld Extended New Massive Gravity
In this paper we find different types of black holes for the Born-Infeld
extended new massive gravity. Our solutions include (un)charged warped (A)dS
black holes for four and six derivative expanded action. We also look at the
black holes in unexpanded BI action. In each case we calculate the entropy,
angular momentum and mass of the black holes. We also find the central charges
for the CFT duals.Comment: 23 pages, 5 figure
