圈由它们的控制多项式决定

Cycles are determined by their domination polynomials

Saieed Akbari, Mohammad Reza Oboudi

摘要:

设$G$是阶为$n$的单图. $G$的支配集是$G$的顶点的集合$S$,使得$G$的每个顶点要么在$S$中,要么与$S$中的顶点相邻。$G$的控制多项式是多项式$D(G,x)=\sum_{i=1}^{n} d(G,i) x^{i}$,其中$d(G,i)$是大小为$i$的$G$的控制集的数目。本文证明了圈是由它们的控制多项式决定的。

英文摘要:

Let $G$ be a simple graph of order $n$. A dominating set of $G$ is a set $S$ of vertices of $G$ so that every vertex of $G$ is either in $S$ or adjacent to a vertex in $S$. The domination polynomial of $G$ is the polynomial $D(G,x)=\sum_{i=1}^{n} d(G,i) x^{i}$, where $d(G,i)$ is the number of dominating sets of $G$ of size $i$. In this paper we show that cycles are determined by their domination polynomials.
