考虑在具有磁电荷 (p^I,q_I) 的卡拉比-丘黑洞的近地平线吸引子几何结构中寻找超对称膜构型的问题。半 BPS 配置对于全局 AdS2 坐标的某些选择是静态的，可用于基本上具有任何四维电荷 (u^I,v_I) 的包裹膜配置。任何包裹膜的集合也可以找到半 BPS 多膜构型，前提是它们的电荷与黑洞电荷的辛内积 p^Iv_I-u^Iq_I 具有相同的符号。这与闵可夫斯基问题形成鲜明对比，在闵可夫斯基问题中，相互保留的超对称性需要所有电荷向量的对齐。全局 AdS2 中膜的径向位置由其中心电荷的相位决定。
The problem of finding supersymmetric brane configurations in the near-horizon attractor geometry of a Calabi-Yau black hole with magnetic-electric charges (p^I,q_I) is considered. Half-BPS configurations, which are static for some choice of global AdS2 coordinate, are found for wrapped brane configurations with essentially any four-dimensional charges (u^I,v_I). Half-BPS multibrane configurations can also be found for any collection of wrapped branes provided they all have the same sign for the symplectic inner product p^Iv_I-u^Iq_I of their charges with the black hole charges. This contrasts with the Minkowski problem for which a mutually preserved supersymmetry requires alignment of all the charge vectors. The radial position of the branes in global AdS2 is determined by the phase of their central charge.
