某些已知图的字典序积的度量维数

Metric dimension of lexicographic product of some known graphs

Mohsen Jannesari

摘要:

对于一个有序集合W = {w1,w2,...,wk}和一个连通图G中的顶点v,则有序k-向量r(v| W):=(d(v,w1),d(v,w2),.,d(v,wk))称为v关于W的(度量)表示,其中d(x,y)是顶点x和y之间的距离。集合W称为G的分解集,如果G的不同顶点关于W有不同的表示。G的分解集的最小基数是它的度量维数。本文研究了图G与H的字典序积G[H]的度量维数。

英文摘要:

For an ordered set W = {w1,w2,...,wk} of vertices and a vertex v in a connected graph G, the ordered k-vector r(v|W) := (d(v,w1),d(v,w2),...,d(v,wk)) is called the (metric) representation of v with respect to W, where d(x,y) is the distance between the vertices x and y. The set W is called a resolving set for G if distinct vertices of G have distinct representations with respect to W. The minimum cardinality of a resolving set for G is its metric dimension. In this paper, we investigate the metric dimension of the lexicographic product of graphs G and H, G[H] for some known graphs.
