Independent [1,2]-number versus independent domination number [PDF]

open access: yesAnalele Universitatii "Ovidius" Constanta - Seria Matematica, 2017
Abstract A [1; 2]-set S in a graph G is a vertex subset such that every vertex not in S has at least one and at most two neighbors in it. If the additional requirement that the set be independent is added, the existence of such sets is not guaranteed in every graph. In this paper we provide local conditions, depending on the degree of

On domination and independent domination numbers of a graph [PDF]

open access: yesDiscrete Mathematics, 1978
AbstractFor a graph G, the definitions of domination number, denoted γ(G), and independent domination number, denoted i(G), are given, and the following results are obtained:Theorem. If G does not have an induced subgraph isomorphic to K1,3, then γ(G) = i(G).Corollary 1. For any graph G, γ(L(G))=i(L(G)), where L(G) is the line graph of G. (This extends

Graphs with equal domination and independent domination numbers [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let γ(G) and i(G) denote the domination number and independent domination number of a graph G. In this article, we establish a sufficient condition for a graph G to satisfy which yields some of the well known classical theorems as corollaries. Further, we also construct several families of graphs G satisfying γ(G) = i(G) using the sufficient condition.

Graphs with equal Grundy domination and independence number

open access: yesDiscrete Optimization, 2023
The Grundy domination number, ${γ_{\rm gr}}(G)$, of a graph $G$ is the maximum length of a sequence $(v_1,v_2,\ldots, v_k)$ of vertices in $G$ such that for every $i\in \{2,\ldots, k\}$, the closed neighborhood $N[v_i]$ contains a vertex that does not belong to any closed neighborhood $N[v_j]$, where ...

On the Number of k‐Dominating Independent Sets [PDF]

open access: yesJournal of Graph Theory, 2016
AbstractWe study the existence and the number of k‐dominating independent sets in certain graph families. While the case namely the case of maximal independent sets—which is originated from Erdős and Moser—is widely investigated, much less is known in general.
