A note on ideals in derived geometries

Boston College(波士顿学院);University of Regensburg(雷根斯堡大学)

Zachary Gardner, Jeroen Hekking

AI总结:

本文研究导出几何中理想理论,比较不同完备性概念,构建导出方案理论图像,并探讨非连通性仿射 morphism 的变形空间性质。

摘要:

我们发展了针对给定导出代数上下文中的堆栈的导出准 coherent 理想的基本理论。我们比较了不同关于导出理想而言的adic 完整性概念,定义并比较了沿闭浸入沿形式谱和形式完备化,将导出理想理论与导出扩展Rees代数理论联系起来。第一个应用是构造导出方案理论图像的普遍性。我们进一步证明任何非连通性仿射导出堆栈 morphism 的变形空间在基上非连通性仿射。最后,我们对这一更一般背景下转置上同调及其滤子进行初步探索。

英文摘要:

We develop the basic theory of derived quasi-coherent ideals for stacks relative to a given derived algebraic context. We compare different notions of adic completeness with respect to derived ideals, define and compare formal spectra and formal completions along closed immersions, and connect the theory of derived ideals to that of derived extended Rees algebras. A first application is the construction of derived scheme-theoretic images in full generality. We further show that the deformation space of any nonconnectively affine morphism of derived stacks is nonconnectively affine over the base. We close with a first exploration of transmutation cohomology and filtrations thereof in this more general context.
