Maker-Breaker domination number [PDF]

open access: yesBulletin of the Malaysian Mathematical Sciences Society, 2019
The Maker-Breaker domination game is played on a graph $G$ by Dominator and Staller. The players alternatively select a vertex of $G$ that was not yet chosen in the course of the game.

Bounds on the Locating-Domination Number and Differentiating-Total Domination Number in Trees

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A subset S of vertices in a graph G = (V,E) is a dominating set of G if every vertex in V − S has a neighbor in S, and is a total dominating set if every vertex in V has a neighbor in S.

On the equality of domination number and 2-domination number

open access: yesDiscussiones Mathematicae Graph Theory
The 2-domination number $ _2(G)$ of a graph $G$ is the minimum cardinality of a set $ D \subseteq V(G) $ for which every vertex outside $ D $ is adjacent to at least two vertices in $ D $. Clearly, $ _2(G) $ cannot be smaller than the domination number $ (G) $. We consider a large class of graphs and characterize those members which satisfy $ _2=

On the edge geodetic and edge geodetic domination numbers of a graph [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2020
In this paper, we study both concepts of geodetic dominating and edge geodetic dominating sets and derive some tight upper bounds on the edge geodetic and the edge geodetic domination numbers.

The paired-domination and the upper paired-domination numbers of graphs [PDF]

open access: yesOpuscula Mathematica, 2015
In this paper we continue the study of paired-domination in graphs. A paired-dominating set, abbreviated PDS, of a graph \(G\) with no isolated vertex is a dominating set of vertices whose induced subgraph has a perfect matching.

On the Paired-Domination Subdivision Number of a Graph

open access: yesMathematics, 2021
In order to increase the paired-domination number of a graph G, the minimum number of edges that must be subdivided (where each edge in G can be subdivided no more than once) is called the paired-domination subdivision number sdγpr(G) of G.

Domination Subdivision Numbers

open access: yesDiscussiones Mathematicae Graph Theory, 2001
A set \(S\) of vertices of a graph \(G\) is a dominating set if every vertex of \(V(G)-S\) is adjacent to some vertex in \(S\). The domination number \(\gamma(G)\) is the minimum cardinality of a dominating set of \(G\), and the domination subdivision number \(\text{sd}_{\gamma}(G)\) is the minimum number of edges that must be subdivided (each edge in \
