Rinovia Simanjuntak, Saladin Uttunggadewa, Suhadi Wido Saputro

摘要:

一个顶点集$S$分解一个图$G$,如果每个顶点都由它到$S$中顶点的距离向量唯一确定。$G$的度量维数是$G$的分解集的最小基数。设$\{G_1, G_2, \ldots, G_n\}$是一个有限图集,每个$G_i$有一个固定的顶点$v_{0_i}$或固定的边$e_{0_i}$,分别称为终端顶点或终端边. $G_1, G_2, \ldots, G_n$的\emph{vertex-amalgamation}(用$Vertex-Amal\{G_i;v_{0_i}\}$表示)是通过取所有的$G_i$并标识它们的终端顶点而形成的。类似地,$G_1, G_2, \ldots, G_n$的\emph{edge-amalgamation}(用$Edge-Amal\{G_i;e_{0_i}\}$表示)是通过取所有的$G_i$并识别它们的终端边缘而形成的.本文研究了任意图的有限集合的点合并和边合并的度量维数。我们给的尺寸的下限和上限,显示的界限是紧的,并构建无限多的图之间的界限的每个可能的值。

英文摘要:

A set of vertices $S$ resolves a graph $G$ if every vertex is uniquely determined by its vector of distances to the vertices in $S$. The metric dimension of $G$ is the minimum cardinality of a resolving set of $G$. Let $\{G_1, G_2, \ldots, G_n\}$ be a finite collection of graphs and each $G_i$ has a fixed vertex $v_{0_i}$ or a fixed edge $e_{0_i}$ called a terminal vertex or edge, respectively. The \emph{vertex-amalgamation} of $G_1, G_2, \ldots, G_n$, denoted by $Vertex-Amal\{G_i;v_{0_i}\}$, is formed by taking all the $G_i$'s and identifying their terminal vertices. Similarly, the \emph{edge-amalgamation} of $G_1, G_2, \ldots, G_n$, denoted by $Edge-Amal\{G_i;e_{0_i}\}$, is formed by taking all the $G_i$'s and identifying their terminal edges. Here we study the metric dimensions of vertex-amalgamation and edge-amalgamation for finite collection of arbitrary graphs. We give lower and upper bounds for the dimensions, show that the bounds are tight, and construct infinitely many graphs for each possible value between the bounds.
