论文摘要
为了理解$ ads_4/cft_3 $对应的框架中的扩展-BMS对称性，渐近广告的几何形状是由无效的冲动冲击波构建的，涉及超级移动参数的不连续性。有人认为全息二二元是在特定时间效率上定位在特定时间效率上的二维欧几里德缺陷保形场，该场在Sitter SpaceTime上的三维形式保形场理论中。缺陷保形场理论产生了Virasoro代数的自然作用。曲率的巨大半径限制$ \ ell \ to \ infty $可产生非平凡的扩展-BMS费用的空间。
With a view to understanding extended-BMS symmetries in the framework of the $AdS_4/CFT_3$ correspondence, asymptotically AdS geometries are constructed with null impulsive shockwaves involving a discontinuity in superrotation parameters. The holographic dual is proposed to be a two-dimensional Euclidean defect conformal field localized on a particular timeslice in a three-dimensional conformal field theory on de Sitter spacetime. The defect conformal field theory generates a natural action of the Virasoro algebra. The large radius of curvature limit $\ell\to\infty$ yields spacetimes with nontrivial extended-BMS charges.
