论文摘要
我描述了在超级移动下无穷大的重力场的施瓦兹式行为，被理解为\ textit {textit {nockable}。为此，我审查了null无穷大的几何形状以及特征是引力辐射的量规不变的新闻张量。我讨论了对天体全息计划的潜在重要含义，特别表明广告的提升$ _3 $/cft $ _2 $对应关系与不可观察的量规部门直接相关。
I describe the Schwarzian behavior of the gravitational field at null infinity under superrotations, to be understood as an \textit{unobservable} gauge artifact. To this end I review the induced geometry of null infinity and the construction of the gauge-invariant News tensor that characterizes gravitational radiation. I discuss potentially important implications for the celestial holography program, suggesting in particular that the uplift of the AdS$_3$/CFT$_2$ correspondence directly relates to the unobservable gauge sector.
