论文摘要
我们在较高的尺寸中重新审视渐近对称性的状态，并提出了超出线性重力的超级移动电荷的定义。我们证明，超级移动电荷在渐近平坦的几何形状空间上存在明确定义的时空动作。此外，我们证明了与超级移动电荷相关的病房身份遵循了均衡的软重力定理，该定理是通用的约束（$ d> 4 $）以及领先的软重力定理。
We revisit the status of asymptotic symmetries in higher even dimensions and propose a definition of superrotation charge beyond linearized gravity. We prove that there is a well-defined spacetime action of the superrotation charge on the space of asymptotically flat geometries. Additionally, we demonstrate that the Ward identity associated with superrotation charges follows from the subleading soft graviton theorem, which is a universal constraint (in $d> 4$) along with the leading soft graviton theorem.
