论文摘要
超级Brane解决方案允许将广义类型的kaluza-klein减少到brane worldvolumes上。 RICCI-FLAT度量标准对平坦的WorldVolume度量的替代构成了起始高维超级强度理论的一致kaluza-klein截断，直到低维纯重力理论。 本文展示了如何扩展这种Brane-worldvolume纯 - 重力一致的截断，以使IIB型D3-Brane型和M理论/IIA型M5-Brane的完整非线性超级重力理论。原始平面“骨架” brane的不间断的超对称性给出了世界volume超对称性的扩展。还显示了与进一步的WorldVolume对角和横向垂直尺寸减小的兼容性，提供了骨架D3-和M5-Branes所有后代的Brane-Worldvolume超级嵌入。举例说明了嵌入到相应的高维超级实力中的Brane-Worldvolume超级溶液。
Supergravity brane solutions allow for a generalised type of Kaluza-Klein reduction onto brane worldvolumes. The known replacement of a flat worldvolume metric by a Ricci-flat metric constitutes a consistent Kaluza-Klein truncation of the starting higher-dimensional supergravity theory down to a lower-dimensional pure gravity theory. This paper shows how to extend such a brane-worldvolume pure-gravity consistent truncation to that for a full nonlinear supergravity theory for the Type IIB D3-brane and the M-theory/Type IIA M5-brane. The extension of worldvolume supersymmetry is given by the unbroken supersymmetry of the original flat "skeleton" brane. Compatibility with further worldvolume diagonal and transverse vertical dimensional reductions is also shown, providing the brane-worldvolume supergravity embeddings of all descendants of the skeleton D3- and M5-branes. Examples are given of brane-worldvolume supergravity solutions embedded into the corresponding higher-dimensional supergravities.
