On graphs whose domination numbers equal their independent domination numbers

open access: yesElectronic Notes in Discrete Mathematics, 2003
Abstract In this paper, we extend a result due to R. B. Allan and R. C. Laskar on graphs whose independent domination numbers equal their domination numbers. We will consider finite simple graphs as treated in most of the standard text-books on Graph Theory (e.g., see D. B. West [1]). Let G = (V,E) be any graph and D ⊆ V. We let N(D) denote the set

On Independent Domination in Planar Cubic Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A set S of vertices in a graph G is an independent dominating set of G if S is an independent set and every vertex not in S is adjacent to a vertex in S.

Independent partial domination

open access: yesCubo, 2021
For $p\in(0,1]$, a set $S\subseteq V$ is said to $p$-dominate or partially dominate a graph $G = (V, E)$ if $\frac{|N[S]|}{|V|}\geq p$. The minimum cardinality among all $p$-dominating sets is called the $p$-domination number and it is denoted by ...

Changing and Unchanging 2-Rainbow Independent Domination

open access: yesIEEE Access, 2019
Domination number is of practical interest in several theoretical and applied scenes. In the problem of wireless networking, the dominating idea is used to deduce an efficient route within the adhoc mobilenetworks.

An upper bound on the total outer-independent domination number of a tree [PDF]

open access: yesOpuscula Mathematica, 2012
A total outer-independent dominating set of a graph \(G=(V(G),E(G))\) is a set \(D\) of vertices of \(G\) such that every vertex of \(G\) has a neighbor in \(D\), and the set \(V(G) \setminus D\) is independent.

Domination and independence subdivision numbers of graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2000
A subset \(S\) of the vertex set \(V(G)\) of a graph \(G\) is called dominating in \(G\), if each vertex of \(G\) either is in \(S\), or is adjacent to a vertex of \(S\). A set \(S\subseteq V(G)\) is independent in \(G\), if no two vertices of \(S\) are adjacent in \(G\).

A note on domination and independence-domination numbers of graphs

open access: yesArs Mathematica Contemporanea, 2012
Vizing's conjecture is true for graphs G satisfying γ i ( G ) = γ ( G ), where γ ( G ) is the domination number of a graph G and γ i ( G ) is the independence-domination number of G , that is, the maximum, over all independent sets I in G , of the minimum number of vertices needed to dominate I . The equality γ i ( G ) = γ (

Independent Dominator Sequence Number of a Graph

open access: yesProcedia Computer Science, 2015
AbstractLet G = (V, E) be a connected graph. A dominator sequence in G is a sequence of vertices S = (v1, v2,. . ., vk) such that for each i with 2 ≤ i ≤ k, the vertex vi dominates at least one vertex which is not dominated by v1, v2,. . ., vi−1. If further the set of vertices in S is an independent set, then S is called an independent dominator ...

An improvement on the maximum number of ‐dominating independent sets [PDF]

open access: yesJournal of Graph Theory, 2018
AbstractErdős and Moser raised the question of determining the maximum number of maximal cliques or, equivalently, the maximum number of maximal independent sets in a graph on vertices. Since then there has been a lot of research along these lines.A ‐dominating independent set is an independent set such that every vertex not contained in has at ...
