移位泊松结构的AKSZ构造

AKSZ construction for shifted Poisson structures

Nikola Tomić

AI总结:

本文证明了移位泊松结构的AKSZ定理,通过等价关系将移位泊松结构与拉格朗日增厚联系起来,并扩展了其定义到导出预堆栈,应用于映射堆栈和BV形式化中。

摘要:

我们证明了移位泊松结构的AKSZ定理:如果X是一个n-移位的导出堆栈,Y是一个d-定向的导出堆栈,那么映射堆栈\u2022Map(Y,X)自然地带有(n-d)-移位的泊松结构。为此,我们证明了n-移位的泊松结构的数据等同于其(n+1)-移位的拉格朗日增厚数据。我们还扩展了移位泊松结构的定义到具有变形理论的导出预堆栈,并给出了两个应用,一个是对非proper源的映射堆栈,另一个是在BV形式化中。

英文摘要:

We prove the AKSZ theorem for shifted Poisson structures: if $X$ is an $n$-shifted Poisson derived stack, and $Y$ a $d$-oriented derived stack, then the mapping stack \[\underline{\mathrm{Map}}(Y,X)\] is naturally endowed with an $(n-d)$-shifted Poisson structure. For this, we prove that the data of an $n$-shifted Poisson structure on a derived Artin stack is equivalent to the data of an $(n+1)$-shifted Lagrangian thickening of it. We also extend the definition of shifted Poisson structures to derived prestacks having a deformation theory and give two applications, one for mapping stacks with a non-proper source and one in BV formalism.
