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

The independent domination number of a random graph [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2011
We prove a two-point concentration for the independent domination number of the random graph Gn,p provided p 2 ln(n) 64ln((lnn)=p). occurs asymptotically almost surely (a.a.s.) if P(Gn;p has property A) ! 1 as n ! 1 . See Bollobas (2) for notation and terminology. Weber (7) showed if p = 1=2 then a.a.s. (Gn;p) is either blog2 n − log2(log2 nlnn)c + 1

On independent domination number of regular graphs

open access: yesDiscrete Mathematics, 1999
A subset \(S\) of the vertex set of a graph \(G\) is called independent, if no two of its vertices are adjacent in \(G\). An independent set in \(G\) is maximal, if it is not a proper subset of another independent set of \(G\). The minimum number of vertices of a maximal independent set is the independent domination number \(i(G)\) of \(G\).

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.
