摘要
在本文中,我们从真空爱因斯坦方程的大- 展开中提取出一个动力学系统,该系统支配无穷多个高自旋荷的时间演化。经积分后,我们在引力相空间上计算这些荷的正则作用。将该作用截断至二次阶及相应的荷守恒律,给出了一座无穷高的软定理塔。我们证明,高自旋荷在共形初基基底下对引力子以及共形软引力子的正则作用,重现了由算子乘积展开导出的高自旋天对称。最后,我们给出直接证据,表明这些荷在引力相空间上构成了 圈代数的正则表示。

30 pages + appendices; v2 Added a section on the exact match between the linearized Einstein's equations and the charge recursion relation. Included details on the relation between the tower of sub-leading components of the $\Psi_0$ Weyl scalar, the Newman-Penrose charges and the higher-spin charges and identified these Weyl scalar components in the associated celestial diamonds
