论文摘要
扁平空间全息需要对BMS对称性有透彻的了解。我们介绍了$ \ mathfrak {bms} _3 $代数的最高权重表示的振荡器构造，并表明它与有关$ \ mathfrak {bms} _3 _3 $模块的已知结果一致。我们利用此框架来证明$ \ mathfrak {bms} _3 $ -Blocks在半古典限制中指数，其中中央费用之一很大。在此上下文中，我们对扰动和重度真空$ \ mathfrak {bms} _3 $ -Blocks计算。
Flat-space holography requires a thorough understanding of BMS symmetry. We introduce an oscillator construction of the highest-weight representation of the $\mathfrak{bms}_3$ algebra and show that it is consistent with known results concerning the $\mathfrak{bms}_3$ module. We take advantage of this framework to prove that $\mathfrak{bms}_3$-blocks exponentiate in the semi-classical limit, where one of the central charges is large. Within this context, we compute perturbatively heavy, and heavy-light vacuum $\mathfrak{bms}_3$-blocks.
