标题： Interplay of Intersecting Branes and Consistent Embeddings

摘要： 我们探讨从10维/11维超引力理论到膜世界体积上的超引力理论的一致截断。 这些低维理论的超对称黑洞膜解可以提升到10维/11维超引力中，并被解释为具有特定弥散模式的相交膜解。 我们综述了这一新型相交膜解族，其中也包括与之前已知的一致截断无关的情况。 反过来，我们认为这些解的知识使我们能够生成适当的一致截断嵌入假设。 我们通过推导纯5维$\mathcal{N}=4$超引力在IIA理论中的D4膜上的新一致嵌入，以及纯6维$\mathcal{N}=(1,1)$超引力在IIB理论中的NS5膜上的新一致嵌入来证明这一点。 显示英文摘要

摘要： We explore consistent truncations from 10d/11d supergravity to supergravity theories on brane worldvolumes. Supersymmetric black-brane solutions to these lower-dimensional theories can be uplifted to 10d/11d supergravity and interpreted as intersecting-brane solutions with a particular smearing pattern. We survey this novel family of intersecting-brane solutions which also includes cases that are not related to previously known consistent truncations. Turning the argument on its head, we argue that the knowledge of such solutions allows us to generate appropriate embedding ans\"atze for consistent truncations. We demonstrate this by deriving new consistent embeddings of pure 5d $\mathcal{N}=4$ supergravity on D4-branes in type IIA theory and of pure 6d $\mathcal{N}=(1,1)$ supergravity on NS5-branes in type IIB theory.
