摘要

在本文中，我们研究了拓扑霍赫希尔德同调和拓扑循环同调的下降性质。特别是，我们验证了这两个不变式都满足连通 E2 环谱的忠实平坦下降和 1-connective 下降。这分别推广了[6]中 Bhatt-Morrow-Scholze 的一个结果和[11]中 Dundas-Rognes 的一个结果。在此过程中，我们发展了一些关于科巴构造的基本理论，并给出了拓扑霍赫希尔德同调的梅滤波的另一种表述，该表述最初是由 Angelini-Knoll-Salch [3] 提出的。

The May filtration on THH and faithfully flat descent

In this article, we study descent properties of topological Hochschild homology and topological cyclic homology. In particular, we verify that both of these invariants satisfy faithfully flat descent and 1-connective descent for connective

-ring spectra. This generalizes a result of Bhatt–Morrow–Scholze from [6] and a result of Dundas–Rognes from [11], respectively. Along the way, we develop some basic theory for cobar constructions and give an alternative presentation of the May filtration on topological Hochschild homology, originally due to Angelini-Knoll–Salch [3].

期刊介绍： The Journal of Pure and Applied Algebra concentrates on that part of algebra likely to be of general mathematical interest: algebraic results with immediate applications, and the development of algebraic theories of sufficiently general relevance to allow for future applications.
