研究了Calabi-Yau流形上紧化的ii型弦理论中BPS态的存在性/稳定性与四维N = 2超重力下BPS解的对应关系。一些矛盾出现了，我们提出了一个解决方案，考虑复合配置。这反过来又给出了一个光滑有效的场理论描述的衰减在边际稳定性。我们还讨论了与三叉弦的联系，特殊拉格朗日子流形的Joyce跃迁，以及Π-stability。
We investigate the correspondence between existence/stability of BPS states in type-II string theory compactified on a Calabi-Yau manifold and BPS solutions of four-dimensional N = 2 supergravity. Some paradoxes emerge, and we propose a resolution by considering composite configurations. This in turn gives a smooth effective field theory description of decay at marginal stability. We also discuss the connection with 3-pronged strings, the Joyce transition of special lagrangian submanifolds, and Π-stability.
