Abstract

Given a regular representation of a finite group G and a positive integer number n, we construct a (finite) topological space X such that its group of homotopy classes of self-homotopy equivalences E(X) and its group of homeomorphisms Aut(X) are isomorphic to G, and the action of G on the n-th homology group Hn(X) is the regular representation. We also discuss other representations.

实现有限群的正则表达式
给定有限群 G 的正则表达式和正整数 n,我们构建一个(有限)拓扑空间 X,使其自同调等价类群 E(X) 和同构群 Aut(X) 与 G 同构,并且 G 对 n 次同调群 Hn(X) 的作用就是正则表达式。我们还讨论了其他表示。

期刊介绍: The Journal of Algebra is a leading international journal and publishes papers that demonstrate high quality research results in algebra and related computational aspects. Only the very best and most interesting papers are to be considered for publication in the journal. With this in mind, it is important that the contribution offer a substantial result that will have a lasting effect upon the field. The journal also seeks work that presents innovative techniques that offer promising results for future research.
