Upper paired domination versus upper domination [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
A paired dominating set $P$ is a dominating set with the additional property that $P$ has a perfect matching. While the maximum cardainality of a minimal dominating set in a graph $G$ is called the upper domination number of $G$, denoted by $\Gamma(G ...

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 Trees

open access: yesMathematics, 2021
A paired-dominating set of a graph G without isolated vertices is a dominating set of vertices whose induced subgraph has perfect matching. The minimum cardinality of a paired-dominating set of G is called the paired-domination number γpr(G) of G.

A Note on the Paired-Domination Subdivision Number of Trees

open access: yesMathematics, 2021
For a graph G with no isolated vertex, let γpr(G) and sdγpr(G) denote the paired-domination and paired-domination subdivision numbers, respectively. In this note, we show that if T is a tree of order n≥4 different from a healthy spider (subdivided star),

Total Domination Versus Paired-Domination in Regular Graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A subset S of vertices of a graph G is a dominating set of G if every vertex not in S has a neighbor in S, while S is a total dominating set of G if every vertex has a neighbor in S. If S is a dominating set with the additional property that the subgraph

Domination and paired domination in Turiyam graphs with application

open access: yesScientific African
A potent tool in the theory of graphs, the Neutrosophic graph, is used to describe the variety of real-world cases with uncertainty brought on by ambiguous, inconsistent, and unpredictable data.

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.

Minimal Graphs with Disjoint Dominating and Paired-Dominating Sets

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A subset D ⊆ VG is a dominating set of G if every vertex in VG – D has a neighbor in D, while D is a paired-dominating set of G if D is a dominating set and the subgraph induced by D contains a perfect matching.

Paired-domination game played in graphs [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2019
In this paper, we continue the study of the domination game in graphs introduced by Bre{\v{s}}ar, Klav{\v{z}}ar, and Rall [SIAM J. Discrete Math. 24 (2010) 979--991].

Graphs with disjoint dominating and paired-dominating sets

open access: yesOpen Mathematics, 2010
Abstract A dominating set of a graph is a set of vertices such that every vertex not in the set is adjacent to a vertex in the set, while a paired-dominating set of a graph is a dominating set such that the subgraph induced by the dominating set contains a perfect matching.
