AI总结:

本文提出导出微分几何中主∞-丛的高形式连接定义,并通过L∞-代数与更高对称性关系,揭示了其在更高规范理论和超引力中的应用。

摘要:

我们介绍了微分几何中主∞-丛上高形式连接的一般定义。这是通过发展从光滑流形到导出堆栈的映射的正式微分和积分,具有足够的变形理论来实现的。这使得我们可以引入主∞-丛的Atiyah L∞-algebroid,并将其全局截面作为导出高对称群的L∞-代数。我们定义∞-丛上的p-形式连接空间作为其Atiyah L∞-algebroid的阶数为p的分裂空间。我们证明了我们新的导出几何p-形式连接概念恢复了通过Čech-Deligne微分余积定义的已知更高U(1)-丛连接。我们进一步将导出高对称性L∞-代数与更高Courant algebroids联系起来。还提到了在更高规范理论和超引力中的某些应用。

英文摘要:

We introduce a general definition of higher-form connections on principal $\infty$-bundles in differential geometry. These connections are built as infinitesimal parallel transports and thus satisfy the fake-curvature condition. We achieve this by developing the formal differentiation and integration of maps from smooth manifolds to derived stacks with sufficient deformation theory. That allows us to introduce the Atiyah $L_\infty$-algebroid of a principal $\infty$-bundle and establish its global sections as the $L_\infty$-algebra of the derived higher symmetry group of the bundle. We define the space of $p$-form connections on an $\infty$-bundle as the space of order $p$ splittings of its Atiyah $L_\infty$-algebroid. This can be cast equivalently as lifting the classifying map of a bundle on a manifold to the order $p$ truncation of the de Rham stack of the manifold. We demonstrate that our new concept of derived geometric $p$-form connections recovers the known notion of connections on higher U(1)-bundles defined via Čech-Deligne differential cocycles. We further relate the $L_\infty$-algebras of derived higher symmetries of higher U(1)-bundles and higher Courant algebroids. Some applications in higher gauge theory and in supergravity are mentioned.
