关于数字H空间

On digital H-spaces

Wayne A. Johnson, Dae-Woong Lee, P. Christopher Staecker

AI总结:

该研究在数字拓扑的图论模型中探究数字H空间的性质,分析其在NP₁、NP₂乘积邻接关系下的代数特性,给出通用构造方法并证明其可分类所有NP₂-数字H空间,还解决了遗留问题、完成数字拓扑群的完整分类。

摘要:

本文在数字拓扑的图论模型中研究数字H空间的性质。与已有研究一致,所得结果通常从根本上取决于NP₁与NP₂乘积邻接关系的选择。我们探究了数字H空间在数字同伦等价下保持的代数性质,并给出一种通用构造方法,可生成在两个范畴中均与数字拓扑群不同伦等价的数字H空间实例。此外,我们证明该构造本质上可对所有NP₂-数字H空间进行分类。在简短的附录中,我们解决了文献[17]中遗留的一个问题,完成了数字拓扑群的完整分类。

英文摘要:

In this article, we investigate properties of digital H-spaces in the graph theoretic model of digital topology. As in prior work, the results obtained often depend fundamentally on the choice between NP$_1$ and NP$_2$ product adjacencies. We explore algebraic properties of digital H-spaces preserved under digital homotopy equivalence, and we give a general construction that produces examples of digital H-spaces which are not homotopy-equivalent to digital topological groups in both categories. Further, we show that this construction essentially classifies all NP$_2$-digital H-spaces. In a short appendix, we resolve a question that was left unresolved in [17], and complete the full classification of digital topological groups.
