我们系统地构建了 1+1 维 (0,4) 共形场论的对偶几何，这些几何是在 M 理论的 S^1 x CY_3 紧致化中包裹的 M5 膜的低能量描述中出现的。这包括大量渐进至 AdS_3 x S^2 的多中心黑洞束缚态。此外，我们发现许多几何形状形成多个相互解耦的 AdS_3 x S^2 喉部。我们认为，解空间的连通分量与 IIA 型吸引子流树的特定限制之间存在有用的一一对应关系。我们指出小型超对称 BTZ 黑洞在 S^2 上的局域化存在热力学不稳定性，这是众所周知的 AdS-Schwarzschild 局域化不稳定性的超对称且完全可解的模拟，并用四个维度的“熵之谜”来识别这一点。我们讨论了这表明的相变，并开始对这些结果进行 CFT 解释。
We systematically construct the geometries dual to the 1+1 dimensional (0,4) conformal field theories that arise in the low-energy description of wrapped M5-branes in S^1 x CY_3 compactifications of M-theory. This includes a large number of multicentered black hole bound states asymptotic to AdS_3 x S^2. In addition, we find many geometries that develop multiple, mutually decoupled AdS_3 x S^2 throats. We argue there is a useful one to one correspondence between the connected components of the space of solutions and particular limits of type IIA attractor flow trees. We point out that there is a thermodynamic instability of small supersymmetric BTZ black holes to localization on the S^2, a supersymmetric and exactly solvable analog of the well known AdS-Schwarzschild localization instability, and identify this with the "Entropy Enigma" in four dimensions. We discuss the phase transition this suggests, and initiate the CFT interpretation of these results.
