Conserved Charges in Even Dimensional Asymptotically locally Anti-de Sitter Space-times
Rong-Gen Cai, Li-Ming Cao
Abstract
Based on the recent paper hep-th/0503045, we derive a formula of calculating conserved charges in even dimensional asymptotically locally anti-de Sitter space-times by using the definition of Wald and Zoupas. This formula generalizes the one proposed by Ashtekar et al. Using the new formula we compute the masses of Taub-Bolt-AdS space-times by treating Taub-Nut-AdS space-times as the reference solution. Our result agrees with those resulting from "background subtraction" method or "boundary counterterm" method. We also calculate the conserved charges of Kerr-Taub-Nut-AdS solutions in four dimensions and higher dimensional Kerr-AdS solutions with Nut charges. The mass of (un)wrapped brane solutions in any dimension is given.
