摘要

摘要如果一个图顶点的集合（set$ J_k$ of graph vertices）的顶点是成对相邻的，并且每个不在（J_k \）中的顶点都至少与（J_k \）中的（k \）顶点相邻，那么这个图顶点的集合（set$ J_k \））就被称为（（k \）-主导独立集（（k \geq 1 \））。在本文中，我们得到了一些平面图类中(k\geq 2 $的(k\)支配独立集的数量的新上限。

On the Number of $$ k $$ -Dominating Independent Sets in Planar Graphs

Abstract

A set $ J_k $ of graph vertices is said to be $ k $-dominating independent ( $ k \geq 1 $) if its vertices are pairwise adjacent and every vertex not in $ J_k $ is adjacent to at least $ k $ vertices in $ J_k $. In the present paper, we obtain new upper bounds for the number of $ k $-dominating independent sets for $ k \geq 2 $ in some planar graph classes.
