摘要：

受沼泽地计划的启发，我们证明了复维数$d\leq4$的Calabi-Yau流形的模空间的Weil-Petersson几何是引力瞬子（即物质引力运动的欧几里得方程的有限作用解）。更准确地说，卡-丘$d$ -折叠（$d\leq4$）的模量几何描述了耦合到标准手征模型的（E）AdS爱因斯坦引力的瞬子。从卡-丘$X$上紧化的弦/M理论的低能物理学观点看，在其模空间上传播的各种场是出现在有效拉格朗日量$\mathscr{L}_\text{eff}$中的耦合。

英文摘要：

Motivated by the swampland program, we show that the Weil-Petersson geometry of the moduli space of a Calabi-Yau manifold of complex dimension $d\leq4$ is a gravitational instanton (i.e. a finite-action solution of the Euclidean equations of motion of gravity with matter). More precisely, the moduli geometry of Calabi-Yau $d$-folds ($d\leq4$) describes instantons of (E)AdS Einstein gravity coupled to a standard chiral model. From the point of view of the low-energy physics of string/M-theory compactified on the Calabi-Yau $X$, the various fields propagating on its moduli space are the couplings appearing in the effective Lagrangian $\mathscr{L}_\text{eff}$.
