AI总结:

本文总结十一维超引力 N=1 紧致化至 AdS₃ 的叶状方法,分析手征子集、奇异叶状结构及其纵向 G₂ 几何与 Morse 形式下的拓扑。

摘要:

我们总结了十一维超引力在八维流形 M 上紧致化至 AdS₃ 空间的 N=1 情形的叶状方法,其中超对称生成元的内部部分 ξ 在 M 的某个真子集 W 上具有手征性。在此情况下,一条拓扑不可行定理意味着补集 M\W 必须是稠密开子集,而 M 容许一个奇异叶状结构 F̄(Haefliger 意义下),该结构由闭一形式 ω 定义,并被赋予纵向 G₂ 结构。此叶状结构的几何由超对称条件决定。我们还描述了当 ω 为 Morse 形式时 F̄ 的拓扑。

英文摘要:

We summarize the foliation approach to ${\cal N}=1$ compactifications of eleven-dimensional supergravity on eight-manifolds $M$ down to $\mathrm{AdS}_3$ spaces for the case when the internal part $ξ$ of the supersymmetry generator is chiral on some proper subset ${\cal W}$ of $M$. In this case, a topological no-go theorem implies that the complement $M\setminus {\cal W}$ must be a dense open subset, while $M$ admits a singular foliation ${\bar {\cal F}}$ (in the sense of Haefliger) which is defined by a closed one-form $\boldsymbolω$ and is endowed with a longitudinal $G_2$ structure. The geometry of this foliation is determined by the supersymmetry conditions. We also describe the topology of ${\bar {\cal F}}$ in the case when $\boldsymbolω$ is a Morse form.
