多面体积空间的上同调代数

The cohomology algebra of polyhedral product spaces

Qibing Zheng

摘要:

本文计算了所有同调分裂多面体积空间的上同调环和所有多面体积空间域上的上同调代数。作为应用,我们给出了两个多面体积空间,使得包含映射诱导的上同调同态相同,但这两个多面体积空间的上同调环不同构。

英文摘要:

In this paper, we compute the cohomology ring of all homology split polyhedral product spaces and the cohomology algebra over a field of all polyhedral product spaces. As an application, we give two polyhedral product spaces such that all the cohomology homomorphisms induced by inclusion map are the same, but the cohomology rings of the two polyhedral product spaces are not isomorphic.
