本文描述了三个解析类的无穷多个有质量IIA超引力的超对称解。这三个类通过简单的通用映射联系起来。例如，解（其中是拓扑的）映射到，其中是亏格的黎曼曲面，度量是通过以某种方式扭曲而获得的。这些解可以有定域的D 6或O 6源，以及任意数量的D8-膜。这个案例（以前只知道数字）是一个NS 5-D 6-D8系统的对偶。三维和四维的场论是未知的，但它们的自由度可以在超引力近似下计算出来。这些解决方案的数值“吸引子”的推广，可能是有用的通量紧致的目的。
We describe three analytic classes of infinitely manysupersymmetric solutions of massive IIA supergravity, for. The three classes are related by simple universal maps. For example, thesolutions (whereis topologically) are mapped to, whereis a Riemann surface of genusand the metric onis obtained by distortingin a certain way. The solutions can have localized D6 or O6 sources, as well as an arbitrary number of D8-branes. Thecase (previously known only numerically) is conjecturally dual to an NS5-D6-D8 system. The field theories in three and four dimensions are not known, but their number of degrees of freedom can be computed in the supergravity approximation. Thesolutions have numerical “attractor” generalizations that might be useful for flux compactification purposes.
