摘要

如果每个顶点都至少与 .G 中的两个顶点相邻，则该顶点集为双支配集。如果一个图的双支配集 S 包含一个双支配集，即 S 的双支配集，则称为逆双支配集。本文中，我们获得了一些标准图的反向双支配集的精确值，并建立了一些关于该参数的一般结果。DOI: https://doi.org/10.52783/tjjpt.v45.i03.7347

Inverse Double Domination in Graphs

A vertex set is a double – dominating set, if each vertex is adjacent to at least two vertices in . The minimum cardinality of a double dominating set of G, denoted by is called the double domination number of G. A double dominating set S of a graph is an inverse double dominating set, if contains a double dominating set say of . Then is called an inverse double dominating set. The inverse double domination number of is the minimum cardinality of an inverse double dominating set. In this paper, we obtain exact value of for some standard graphs and also, we establish some general results on this parameters. DOI: https://doi.org/10.52783/tjjpt.v45.i03.7347
