We prove the unrolled superalgebra $\mathcal{U}_{\xi}^{H}\mathfrak{sl}(2|1)$ has a completion which is a ribbon superalgebra in a topological sense where $\xi$ is a root of unity of odd order. Using this ribbon superalgebra we construct its universal invariant of links. We use it to construct an invariant of $3$-manifolds of Hennings type.

来自拓扑 Hopf 超代数的 3 流形的 Hennings 型不变量

我们证明展开的超代数 $\mathcal{U}_{\xi}^{H}\mathfrak{sl}(2|1)$ 有一个完成,它是拓扑意义上的带状超代数,其中 $\xi$ 是奇数阶统一的根。使用这个带状超代数,我们构建了它的链接的通用不变量。我们用它来构造一个 Hennings 类型的 $3$-流形的不变量。
