图的k-元组拓扑数

The k-Tuple Domatic Number of a Graph

Adel P. Kazemi

摘要:

对每个正整数$k$,如果$V-S$的每个顶点与$k$的最少顶点相邻,且$S$的每个顶点与$S$的最少$k-1$顶点相邻,则图$G=(V,E)$中的顶点集$S$是$G$的$k$ -元组控制集. $G$的$k$ -元组控制集的最小基数是$G$的$k$ -元组控制数.当$k=1$,一个$k$ -元组控制数是充分研究的控制数。我们定义$G$的$k$ -元组支配数为$V$划分成$k$ -元组支配集的最大集合数。回想一下,当$k=1$,一个$k$ -元组拓扑数是研究得很好的拓扑数。在这项工作中,我们得到的基本性质和界限的$k$ -元组domatic数。

英文摘要:

For every positive integer $k$, a set $S$ of vertices in a graph $G=(V,E)$ is a $k$-tuple dominating set of $G$ if every vertex of $V-S$ is adjacent to least $k$ vertices and every vertex of $S$ is adjacent to least $k-1$ vertices in $S$. The minimum cardinality of a $k$-tuple dominating set of $G$ is the $k$-tuple domination number of $G$. When $k=1$, a $k$-tuple domination number is the well-studied domination number. We define the $k$-tuple domatic number of $G$ as the largest number of sets in a partition of $V$ into $k$-tuple dominating sets. Recall that when $k=1$, a $k$-tuple domatic number is the well-studied domatic number. In this work, we derive basic properties and bounds for the $k$-tuple domatic number.
