栈上的李群胚与交叉模值格贝

Lie groupoids and crossed module-valued gerbes over stacks

Mohammad Jawad Azimi

摘要:

本文给出了在任意交叉模上和任意微分叠加上的格贝的精确而一般的描述。我们只使用李群胚,因此是普通微分几何。通过与非阿贝尔上同调的比较,我们证明了与已有概念的一致性。

英文摘要:

We give a precise and general description of gerbes valued in arbitrary crossed module and over an arbitrary differential stack. We do it using only Lie groupoids, hence ordinary differential geometry. We prove the coincidence with the existing notions by comparing our construction with non-Abelian cohomology.
