论文摘要
我们介绍并调查了$ \ Mathbb Z $的封面的概念。更确切地说，多纳吉和维滕建议建造第一类阻塞类，以通过差速器操作员分裂超然。我们证明，这种构造的无限延长满足了一些普遍的特性，可以看作是对分级歧管类别中的超人命中的覆盖。
We introduce and investigate the notion of a $\mathbb Z$-graded covering for a supermanifold. More precisely, Donagi and Witten suggested a construction of the first obstruction class for splitting of a supermanifold via differential operators. We prove that an infinite prolongation of this construction satisfies some universal properties and can be seen as a covering of a supermanifold in the category of graded manifolds.
