关于图的Alcuin数的一些新结果

Some New Results in the Alcuin Number of Graphs

Abbas Seify, Hossein Shahmohamad

摘要:

本文证明了关于图的Alcuin数的一些结果。首先,我们对具有唯一最小顶点覆盖的图进行分类。然后,我们提出了两个必要条件的图是第二类,并显示为什么其中之一(条件的公共邻居)是充分的。利用这一分类定理,我们证明了关于第一类图和第二类图的一些结果,如图的笛卡儿积和正则图的分类。

英文摘要:

We prove some results concerning Alcuin number of graphs. First, we classify graphs which have unique minimum vertex cover. Then we present two necessary conditions for a graph to be of class two and show why one of them (condition on common neighbors) is sufficient as well. By using this classification theorem, we prove some results about class one and class two graphs such as cartesian product of graphs and classification of regular graphs.
