论文摘要
我们对一类多态性渐近固定空间的渐近电荷进行了分类，并具有有限的剪切，从而在平滑的渐近流量空位上概括了最新结果。多态空间是正式一致的一类空间，无法满足众所周知的剥离特性。因此，与光滑类别相比，它们构成了一个更加物理的渐近空位。特别是，我们确定广义的保守的非线性纽曼 - 芬罗电荷是在这种空间上存在的，这是渐近BMS电荷的子集。
We classify the asymptotic charges of a class of polyhomogeneous asymptotically-flat spacetimes with finite shear, generalising recent results on smooth asymptotically-flat spacetimes. Polyhomogenous spacetimes are a formally consistent class of spacetimes that do not satisfy the well-known peeling property. As such, they constitute a more physical class of asymptotically-flat spacetimes compared to the smooth class. In particular, we establish that the generalised conserved non-linear Newman-Penrose charges that are known to exist for such spacetimes are a subset of asymptotic BMS charges.
