AI 中文总结

本文将抽象六函子形式主义扩展至Ind-与Pro-范畴,应用于定义ind-pro-代数栈的动机稳定同伦理论,并借助Liu-Zheng的多单纯语言证明上同调纯性的函子性。

AI 中文摘要

本文研究抽象六函子形式主义的两个推论:其一,证明抽象六函子形式主义可扩展到几何构造的特定归纳(Ind-)范畴与投射(Pro-)范畴,应用上可定义ind-pro-代数栈(如赫克栈)的动机稳定同伦理论;其二,利用Liu-Zheng发展的多单纯语言证明上同调纯性具有函子性。

英文摘要

In this article, we study two consequences of abstract six-functor formalisms. Firstly, we show that an abstract six-functor formalism can be extended to specific Ind- and Pro- categories of geometric setups. As an application, we can define the motivic stable homotopy theory for ind-pro-algebraic stacks such as the Hecke stack. Secondly, we also show that Cohomological Purity is functorial using the multisimplicial language developed by Liu-Zheng.
