某些蛛网偏序集有向图的基本性质及问题

Some Cobweb Posets Digraphs' Elementary Properties and Questions

A. K. Kwaniewski

摘要:

合理地表示调度问题的有向图应该是有向无圈图。下面我们将处理一种特殊的分级$DAGs$,名为$KoDAGs$。对于它们的定义和第一个主要性质,请参见$ [1]$,其中定义了有向二分图及其相应邻接矩阵的自然连接,然后应用于研究蛛网偏序集及其$Hasse$有向图,称为$KoDAGs$。在这份报告中,我们扩展了蛛网偏序集的概念,同时提供了一些基本的后果的描述和观察建立在$[1]$。

英文摘要:

A digraph that represents reasonably a scheduling problem should be a directed acyclic graph. Here down we shall deal with special kind of graded $DAGs$ named $KoDAGs$. For their definition and first primary properties see $ [1]$, where natural join of directed biparted graphs and their corresponding adjacency matrices is defined and then applied to investigate cobweb posets and their $Hasse$ digraphs called $KoDAGs$. In this report we extend the notion of cobweb poset while delivering some elementary consequences of the description and observations established in $[1]$.
