On-shell action and the Bekenstein-Hawking entropy of supersymmetric black holes in AdS6 spacetimes

초록

Recently, entropy of static supersymmetric black holes in AdS(6) was microscopically counted by the topologically twisted index of five-dimensional superconformal field theories. However, the AdS/CFT dictionary states that the partition function of the boundary field theory corresponds to the on-shell action of the bulk quantum gravity. In this paper, we aim to explain the microscopic counting of black hole entropy by the topologically twisted index. We calculate the renormalized on-shell action and show that the on-shell action equals the Bekenstein-Hawking entropy of the supersymmetric black holes in AdS(6).
