标题： Gravitational higher-form symmetries and the origin of hidden symmetries in Kaluza-Klein compactifications

摘要： 我们证明，在存在等距变换和非平凡拓扑的情况下，爱因斯坦-希尔伯特作用量在某些度规变换下保持不变，这些变换不是微分同胚。这些变换类似于具有$p$-形式场的场论中的高阶形式对称性。在环面卡鲁扎-克莱因紧化背景下，我们证明这些对称性会产生维度约化理论中的一些“隐藏对称性”（对偶性）。 显示英文摘要

摘要： We show that, in presence of isometries and non-trivial topology, the Einstein--Hilbert action is invariant under certain transformations of the metric which are not diffeomorphisms. These transformations are similar to the higher-form symmetries of field theories with $p$-form fields. In the context of toroidal Kaluza--Klein compactifications, we show that these symmetries give rise to some of the ``hidden symmetries'' (dualities) of the dimensionally-reduced theories.
