扭曲微分上同调

Twisted differential cohomology

Ulrich Bunke, Thomas Nikolaus

摘要:

本文的主要目的是构造扭广义微分上同调理论,并全面地说明它的基本函子性质。技术上,它结合了同伦理论的方法(untwisted)广义微分上同调发展的Hopkins-Singer和后来的第一作者和D。Gepner与Ando-Blumberg-Gepner的扭曲上同调的oo-范畴表示。对给定的广义上同调理论引入了微分扭的概念,构造了扭微分上同调群(分别为:光谱)。本文的主要技术结果是微分扭转的存在性和唯一性。这些结果将应用于各种例子,包括K-理论,拓扑模形式和其他上同调理论。

英文摘要:

The main goal of the present paper is the construction of twisted generalized differential cohomology theories and the comprehensive statement of its basic functorial properties. Technically it combines the homotopy theoretic approach to (untwisted) generalized differential cohomology developed by Hopkins-Singer and later by the first author and D. Gepner with the oo-categorical treatement of twisted cohomology by Ando-Blumberg-Gepner. We introduce the notion of a differential twist for a given generalized cohomology theory and construct twisted differential cohomology groups (resp. spectra). The main technical results of the paper are existence and uniqueness statements for differential twists. These results will be applied in a variety of examples, including K-theory, topological modular forms and other cohomology theories.
