摘要

我们建立了黎曼自旋流形的某种覆盖复杂性概念与其标量曲率正下限之间的关系。这利用了定量算子 $K$ 理论和 Lipschitz 拓扑 $K$ 理论之间的配对，并结合了早先的定量高指数消失定理。

Covering complexity, scalar curvature, and quantitative $K$-theory

We establish a relationship between a certain notion of covering complexity of a Riemannian spin manifold and positive lower bounds on its scalar curvature. This makes use of a pairing between quantitative operator $K$-theory and Lipschitz topological $K$-theory, combined with an earlier vanishing theorem for the quantitative higher index.
