围长至少为5的图中的定位控制集和识别码

Locating-dominating sets and identifying codes in graphs of girth at least 5

Camino Balbuena, Florent Foucaud, Adriana Hansberg

摘要:

定位控制集和识别码是分离系统领域中两个密切相关的概念。粗略地说,它们存在于图的控制集中,使得每个顶点在控制集中由其邻域唯一标识。本文研究了围长至少为5的给定最小度图的最小定位控制集或识别码的大小。我们使用顶点不相交路径的技术来提供这样的集合的最小尺寸的上界,并构造接近满足这些界限的图。

英文摘要:

Locating-dominating sets and identifying codes are two closely related notions in the area of separating systems. Roughly speaking, they consist in a dominating set of a graph such that every vertex is uniquely identified by its neighbourhood within the dominating set. In this paper, we study the size of a smallest locating-dominating set or identifying code for graphs of girth at least 5 and of given minimum degree. We use the technique of vertex-disjoint paths to provide upper bounds on the minimum size of such sets, and construct graphs who come close to meet these bounds.
