路与圈上的识别码与定位控制集

Identifying codes and locating-dominating sets on paths and cycles

Chunxia Chen, Changhong Lu, Zhengke Miao

摘要:

设$G=(V,E)$是一个图,$r\ge 1$是一个整数。对于集合$D \subseteq V$,定义$N_r[x] = \{y \in V: d(x, y) \leq r\}$和$D_r(x) = N_r[x] \cap D$,其中$d(x,y)$表示$x$和$y$之间任何最短路径中的边数。如果对于所有顶点$x\in V$(分别为$x \in V\backslash D$),$D_r(x)$都非空且不同,则$D$称为$r$ -标识码(分别为$r$ -定位-支配集).本文给出了路和奇圈中PDMATHAMV-可识别码的完整结果,也给出了圈中2-定位-控制集的完整结果。

英文摘要:

Let $G=(V,E)$ be a graph and let $r\ge 1$ be an integer. For a set $D \subseteq V$, define $N_r[x] = \{y \in V: d(x, y) \leq r\}$ and $D_r(x) = N_r[x] \cap D$, where $d(x,y)$ denotes the number of edges in any shortest path between $x$ and $y$. $D$ is known as an $r$-identifying code ($r$-locating-dominating set, respectively), if for all vertices $x\in V$ ($x \in V\backslash D$, respectively), $D_r(x)$ are all nonempty and different. In this paper, we provide complete results for $r$-identifying codes in paths and odd cycles; we also give complete results for 2-locating-dominating sets in cycles.
