Independent transversal domination number in complementary prisms

open access: yes, 2021
Summary: A set \(D \subseteq V(G)\) is an independent transversal dominating set of \(G\) if \(D\) is a dominating set and also intersects every maximum independent set in \(G\). The minimum cardinality of such a set is equal to the transversal domination number, denoted by \(\gamma_\mathrm{it}(G)\).

2-Outer-Independent Domination in Graphs [PDF]

open access: yesThe National Academy of Sciences, India, 2015
We initiate the study of 2-outer-independent domination in graphs. A 2-outer-independent dominating set of a graph G is a set D of vertices of G such that every vertex of V (G) \D has at least two neighbors in D, and the set V (G)\D is independent. The 2-

Trees with independent Roman domination number twice the independent domination number

Discrete Mathematics, Algorithms and Applications, 2015
A Roman dominating function (RDF) on a graph [Formula: see text] is a function [Formula: see text] satisfying the condition that every vertex [Formula: see text] for which [Formula: see text] is adjacent to at least one vertex [Formula: see text] for which [Formula: see text].

On Domination and Independence Numbers of Graphs

Results in Mathematics, 1990
The authors characterize those graphs which (1) have equal domination and independence numbers, and (2) are either bipartite or are block graphs, i.e., graphs in which every block is a complete graph.

Domination critical graphs with higher independent domination numbers

Journal of Graph Theory, 1996
Let \(\gamma(G)\) be the domination number of a graph \(G\) and denote by \(i(G)\) its independent domination number. We say that a graph \(G\) is domination critical, if for every edge \(e\in \overline E(G)\), we have \(\gamma(G+ e)< \gamma(G)\). Obviously, \(\gamma(G)\leq i(G)\). It was conjectured that if \(G\) is a domination critical graph with \(\

The domination and independent domination numbers of some families of snarks

Ars Mathematica Contemporanea
It is known that for an arbitrary graph \(G\), determining either its domination number \(\gamma(G)\) or independent domination number \(i(G)\) is an NP-hard problem. Therefore, establishing bounds for and determining these two domination parameters for particular classes of graphs (especially for cubic graphs) received much attention.

Independent Domination Number of Planar Triangulations

Journal of Graph Theory
ABSTRACTWe show that every planar triangulation on vertices has a maximal independent set of size at most . This affirms a conjecture by Botler, Fernandes, and GutiƩrrez (Electron. J. Comb., 2024) based on an open question of Goddard and Henning (Appl. Math. Comput., 2020).
