我们使用blackfold方法来分析M理论中假定的超重力解的性质，该理论描述了在十一维超重力的Cvetic-Gibbons-Lu-Pope背景中极化的反M2膜（即，用负M2膜电荷包裹三个周期的M5膜）的逆反应。在零温度下，我们直接在超重力下恢复了 Klebanov 和 Pufu 的亚稳态。在有限温度下，我们发现了胖或瘦的 M5 膜状态与亚稳态的热化版本之间的合并模式，这种模式是以前未知的。在反膜电荷值足够小时，单个脂肪亚稳态合并遵循最近在 IIB 型超重力的 Klebanov-Strassler 溶液中发现的极化反 D3 膜相同的模式。我们提供了定量证据表明这种合并是由地平线几何特性驱动的。对于较大的反膜电荷值，包裹的 M5 膜溶液表现出不同的有限温度转变模式，这在 Klebanov-Strassler 的反 D3 系统中没有已知的对应模式。
We use blackfold methods to analyse the properties of putative supergravity solutions in M-theory that describe the backreaction of polarised anti-M2 branes (namely, M5 branes wrapping three-cycles with negative M2-brane charge) in the Cvetic-Gibbons-Lu-Pope background of eleven-dimensional supergravity. At zero temperature we recover the metastable state of Klebanov and Pufu directly in supergravity. At finite temperature we uncover a previously unknown pattern of mergers between fat or thin M5-brane states with the thermalised version of the metastable state. At sufficiently small values of the anti-brane charge a single fat-metastable merger follows the same pattern recently discovered for polarised anti-D3-branes in the Klebanov-Strassler solution in type IIB supergravity. We provide quantitative evidence that this merger is driven by properties of the horizon geometry. For larger values of the anti-brane charge the wrapped M5-brane solutions exhibit different patterns of finite-temperature transitions that have no known counterpart in the anti-D3 system in Klebanov-Strassler.
