Xinxing Tang, Shing-Tung Yau

AI总结:

本文在强正则条件下,基于容许条件定义的特殊最小路径,系统引入有向图的胞腔链复形并证明其良定义性,研究胞腔同调性质,并给出示例与观察。

摘要:

在文献[T Y]中,我们研究了在强正则条件下,有向图G的路径复形中的最小路径P及其支撑子有向图Supp(P)的对(P, Supp(P))。本文首先考虑由容许条件(定义[ref])指定的特殊最小路径P,这意味着(P, Supp(P))允许奇异立方实现。基于这样的子集,我们系统地引入了与G相关的胞腔链复形的定义,并证明了其良定义性。然后我们研究了这种胞腔同调的若干性质。最后,我们给出了几个有趣的例子以及一些重要的观察。

英文摘要:

In \cite{TY}, we investigate the pair $(P, \Supp(P))$ of minimal path $P$ and its supporting sub-digraph $\Supp(P)$ in the path complex of a digraph $G$ under the strongly regular condition. In this paper, first, we consider the special minimal path $P$ specified by the admissible condition (Definition \ref{admpair}), which means that $(P,\Supp(P))$ admits a singular cubical realization. Based on such a subset, we systematically introduce the definitions of cellular chain complex associated to $G$ and prove the well-definedness. Then we study several properties of such cellular homologies. Finally, we present several intriguing examples as well as some important observations.
