正数量曲率度量空间的路径分量不变量

Path-component invariants for spaces of positive scalar curvature metrics

David J. Wraith

摘要:

Kreck-Stolz $s$ -不变量是正数量曲率度量空间和模空间的经典路径分量不变量。它是一个绝对的(相对的)不变量,但这种强度是以仅在限制性拓扑条件下定义为代价的。本文的目的是构造一个类似的不变量的某些产品流形上的$s$ -不变量没有定义。

英文摘要:

The Kreck-Stolz $s$-invariant is a classic path-component invariant for the space and moduli space of positive scalar curvature metrics. It is an absolute (as opposed to relative) invariant, but this strength comes at the expense of being defined only under restrictive topological conditions. The aim of this paper is to construct an analogous invariant for certain product manifolds on which the $s$-invariant is not defined.
