渐近引力荷

Asymptotic gravitational charges

Hadi Godazgar, Mahdi Godazgar, Malcolm J. Perry

摘要:

我们提出了一种方法,找到,在原则上,所有的渐近引力荷。其基本思想是,必须考虑对作用量的所有可能的贡献,这些贡献不影响感兴趣的理论的运动方程;这些项包括拓扑项。因此,我们观察到,一阶形式主义是最适合的渐近收费的分析。特别是,这种方法可以用来提供最近发现的对偶电荷的哈密顿推导。

英文摘要:

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.
