论文摘要
我们提供了一种简单的方法，以在渐近地范围内的渐近曲率重力中计算较高的曲率重力中的能量。这是从添加到重力作用中的拓扑用语的联合使用中，以及从增强作用功能中得出的瓦尔德电荷。无需其他边界条款。作为一致性检查，我们表明以这种方式得出的保守量的公式为渐近广告黑洞的质量带来了正确的结果。
We provide a simple method to compute the energy in higher curvature gravity in asymptotically AdS spacetimes in even dimensions. It follows from the combined use of topological terms added to the gravity action, and the Wald charges derived from the augmented action functional. No additional boundary terms are needed. As a consistency check, we show that the formula for the conserved quantities derived in this way yields the correct result for the mass of asymptotically AdS black holes.
