标题： Branes wrapped on quadrilaterals

摘要： 我们构建了超对称AdS$_2\times\mathbb{M}_4$解，这是$D=6$无规超引力的新的解族，以及AdS$_3\times\mathbb{M}_4$解，这是$D=7$无规超引力的新的解族，其中$\mathbb{M}_4$是具有四个固定点的四维环面轨道。 这些解以统一的方式呈现，突出了它们共同的基本几何结构。 $D=6$解释为在D4-branes环绕$\mathbb{M}_4$时，其近视界极限的提升到大质量IIA型并描述，而$D=7$解释为在M5-branes环绕$\mathbb{M}_4$时，其近视界极限的提升到$D=11$超引力并描述。我们通过极化一个由arXiv:2210.16128中提出的轨道奇异引力块构建的函数，重现了这两类的熵和引力中心荷。 显示英文摘要

摘要： We construct new families of supersymmetric AdS$_2\times\mathbb{M}_4$ solutions of $D=6$ gauged supergravity and AdS$_3\times\mathbb{M}_4$ solutions of $D=7$ gauged supergravity, where $\mathbb{M}_4$ are four-dimensional toric orbifolds with four fixed points. These are presented in a unified fashion, that highlights their common underlying geometry. The $D=6$ solutions uplift to massive type IIA and describe the near-horizon limit of D4-branes wrapped on $\mathbb{M}_4$, while the $D=7$ solutions uplift to $D=11$ supergravity and describe the near-horizon limit of M5-branes wrapped on $\mathbb{M}_4$. We reproduce the entropy and gravitational central charge of the two families by extremizing a function constructed gluing the orbifold gravitational blocks proposed in arXiv:2210.16128.
