论文摘要
我们提出了一种原则上查找所有渐近引力电荷的方法。基本思想是，必须考虑对不影响感兴趣理论运动方程的行动的所有可能贡献。这样的术语包括拓扑术语。结果，我们观察到，第一阶形式主义最适合分析渐近电荷。特别是，该方法可用于提供最近发现的双重电荷的哈密顿衍生物。
We present a method for finding, in principle, all asymptotic gravitational charges. The basic idea is that one must consider all possible contributions to the action that do not affect the equations of motion for the theory of interest; such terms include topological terms. As a result we observe that the first order formalism is best suited to an analysis of asymptotic charges. In particular, this method can be used to provide a Hamiltonian derivation of recently found dual charges.
