AI 中文摘要
我们展示了AdS黑洞的视界对称性如何在对偶应力张量动力学的流体动力学作用量中实现。近期获取此类作用量的一种方法涉及视界边界条件的选择，我们证明保持这些条件的微分同胚会产生对应流体动力学作用量的对称性。我们采用该方法得到了JT引力和AdS₃引力中黑洞小振幅扰动的显式流体动力学作用量，并明确证明了这些对称性的存在。对于边界条件的自然选择，所得作用量明显实现了先前为最大混沌有效理论提出的规范对称性。
英文摘要
We demonstrate how horizon symmetries of AdS black holes are realised in the hydrodynamic actions for the dynamics of the dual stress tensor. A recent approach for obtaining such actions involves a choice of horizon boundary conditions, and we show that diffeomorphisms that preserve these give rise to symmetries of the corresponding hydrodynamic action. We obtain explicit hydrodynamic actions for small amplitude perturbations of black holes in JT and AdS$_3$ gravity using this approach and demonstrate explicitly the existence of these symmetries. For a natural choice of boundary conditions, the resulting actions manifestly realise gauge symmetries previously proposed for effective theories of maximal chaos.
