Entropy of extremal warped black holes

.
(February 2009)

Abstract

We study the entropy of extremal warped black hole obtained from the topologically massive gravity with a negative cosmological constant of \$Łambda=-1/l^2\$. We compare the entropy \$S\_e=\alpha/3G\$ from the Wald formalism with \$S\_w=l u /3G\$ from the entropy function approach. These are the same if \$\alpha=l u\$. Also we obtain the same Cardy formula when \$J\_e= l^3 q\$ with \$J\_e\$ the angular momentum and \$q\$ the conserved quantity.
