AI总结:

本文研究了$m$-柱面图$(C_n\Box P_k)\Box P_m$的最小尺寸解析集的计算问题,并探讨了布尔格$BL_n$的子图$H(n)$的线图$L(n)$的解析集、双重解析集和强解析集的最小尺寸。

摘要:

图$G$的解析集是一个顶点集$Q = \{q_1, ..., q_k\}$,使得对于所有$p\in V(G)$,$k$元组$(d(p, q_1), ..., d(p, q_k ))$能唯一确定$p$,其中$d(p, q_i)$被视为图$G$中从$p$到$q_i$的最短路径的最小长度。在本文中,我们考虑对$m$-柱面图$(C_n\Box P_k)\Box P_m$的某些最小尺寸解析集进行计算研究。布尔格$BL_n$($n\geq 1$)是其顶点集为$[n]=\{1,2,...,n\}$的所有子集的集合的图,其中两个子集$X$和$Y$在它们的对称差恰好有一个元素时相邻。在图$BL_n$中,层$L_i$是$[n]$的$i$-子集族。子图$BL_n(i,i+1)$是由层$L_i$和$L_{i+1}$导出的$BL_n$的子图。通常图$BL_n(1,2)$记为$H(n)$。我们研究了图$L(n)$(即$H(n)$的线图)的解析集、双重解析集和强解析集的最小尺寸。

英文摘要:

A resolving set for a graph $G$ is a set of vertices $Q = \{q_1, ..., q_k\}$ such that, for all $p\in V(G)$ the $k$-tuple $(d(p, q_1), ..., d(p, q_k ))$ uniquely determines $p$, where $d(p, q_i)$ is considered as the minimum length of a shortest path from $p$ to $q_i$ in graph $G$. In this paper, we consider the computational study of some resolving sets with the minimum size for the $m$-cylinder graph $(C_n\Box P_k)\Box P_m$. The Boolean lattice $BL_n$, $n\geq 1$, is the graph whose vertex set is the set of all subsets of $[n]=\{1,2,...,n\}$, where two subsets $X$ and $Y$ are adjacent if their symmetric difference has precisely one element. In the graph $BL_n$, the layer $L_i$ is the family of $i$-subsets of $[n]$. The subgraph $BL_n(i,i+1)$ is the subgraph of $BL_n$ induced by layers $L_i$ and $L_{i+1}$. Usually the graph $BL_n(1,2)$ is denoted by $H(n)$. We study the minimum size of a resolving set, doubly resolving set and strong resolving set for the graph $L(n)$, which is the line graph of $H(n)$.
