摘要

图G的支配集是顶点集V的子集D,使得不在V-D中的每个顶点都与顶点子集D中的至少一个顶点相邻。如果D的固有子集不为支配集,则支配集D是最小支配集。这个集合中元素的个数称为图的支配数,用$\gamma(G)$表示。本文通过识别棱镜CL_n、反棱镜Q_n和交叉棱镜R_n的最小控制集,得到了棱镜图族的控制数。

Minimum Dominating Set for the Prism Graph Family
The dominating set of the graph G is a subset D of vertex set V, such that every vertex not in V-D is adjacent to at least one vertex in the vertex subset D. A dominating set D is a minimal dominating set if no proper subset of D is a dominating set. The number of elements in such set is called as domination number of graph and is denoted by $\gamma(G)$. In this work the domination numbers are obtained for family of prism graphs such as prism CL_n, antiprism Q_n and crossed prism R_n by identifying one of their minimum dominating set.
