论文摘要
在抗DE保姆（ADS）空间上的大量田地在其特定质量值的特定值上享受类似Galileon的偏移对称性。我们探讨了如何通过2分函数级别的边界综合场理论（CFT）实现这些移位对称性。在替代量化方案中，双保形场获取较小的$δ_- $保形维度，移位对称性在双CFT中被实现为量规对称性，因此只有移位不变的操作员才是真正的保形主场。在标准量化方案中，移位对称性作用于来源，导致对构成的病房身份采取积分约束的形式。
Massive fields on anti-de Sitter (AdS) space enjoy galileon-like shift symmetries at particular values of their masses. We explore how these shift symmetries are realized through the boundary conformal field theory (CFT), at the level of the 2-point functions. In the alternate quantization scheme in which the dual conformal field gets the smaller $Δ_-$ conformal dimension, the shift symmetry is realized as a gauge symmetry in the dual CFT, so that only shift invariant operators are true conformal primary fields. In the standard quantization scheme the shift symmetry acts on the source, leading to Ward identities that take the form of integral constraints.
