我们介绍了非交换堆栈的分层理论(即,像样的马厩 ∞ 英夫蒂 - 类别),我们证明了一个重建定理,表示他们在他们的地层和胶合数据。这个重建定理与对称monoidal结构相容,并且与更一般的运算结构相容,例如 E n \mathbb {E}_n -monoidal结构。我们还提供了一套基本的操作,从旧的构建新的分层:限制,拉回,商,推进,细化。此外,我们建立了一个对偶形式的重建,这是密切相关的Verdier对偶和反射函子,并给出了莫比乌斯反演的分类。 我们的主要应用是等变稳定同伦理论:对于任何紧李群 G G ,我们给出了一个真正的对称monoidal分层 G G - 光谱。的情况下 G G 是有限的,这表示真正的 G G - 谱的几何不动点(同伦等变谱)和它们之间的粘合数据(由适当的泰特结构给出)。 我们还证明了一个adelic重建定理,这不仅适用于普通的计划,但在更一般的情况下,张量三角几何,在那里我们得到一个对称的monoidal分层的巴耳末谱。我们讨论色同伦理论的特殊例子。
We introduce a theory of stratifications of noncommutative stacks (i.e., presentable stable ∞ \infty -categories), and we prove a reconstruction theorem that expresses them in terms of their strata and gluing data. This reconstruction theorem is compatible with symmetric monoidal structures, and with more general operadic structures such as E n \mathbb {E}_n -monoidal structures. We also provide a suite of fundamental operations for constructing new stratifications from old ones: restriction, pullback, quotient, pushforward, and refinement. Moreover, we establish a dual form of reconstruction; this is closely related to Verdier duality and reflection functors, and gives a categorification of Möbius inversion. Our main application is to equivariant stable homotopy theory: for any compact Lie group G G , we give a symmetric monoidal stratification of genuine G G -spectra. In the case that G G is finite, this expresses genuine G G -spectra in terms of their geometric fixedpoints (as homotopy-equivariant spectra) and gluing data therebetween (which are given by proper Tate constructions). We also prove an adelic reconstruction theorem; this applies not just to ordinary schemes but in the more general context of tensor-triangular geometry, where we obtain a symmetric monoidal stratification over the Balmer spectrum. We discuss the particular example of chromatic homotopy theory.
