Disjoint Paired-Dominating sets in Cubic Graphs [PDF]

open access: yesGraphs and Combinatorics, 2019
A paired-dominating set of a graph G is a dominating set D with the additional requirement that the induced subgraph G[D] contains a perfect matching. We prove that the vertex set of every claw-free cubic graph can be partitioned into two paired-dominating sets.

Total and Paired Domination Stability in Prisms

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A set D of vertices in an isolate-free graph is a total dominating set if every vertex is adjacent to a vertex in D. If the set D has the additional property that the subgraph induced by D contains a perfect matching, then D is a paired dominating set of

Graphical Analysis of Covering and Paired Domination in the Environment of Neutrosophic Information

open access: yes, 2021
Neutrosophic graph (NG) is a powerful tool in graph theory, which is capable of modeling many real-life problems with uncertainty due to unclear, varying, and indeterminate information.

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.

Paired-domination in inflated graphs

open access: yesTheoretical Computer Science, 2004
The paper studies inflated graphs of graphs. If \(G\) is a graph, then the inflated graph \(G_I\) of \(G\) is defined. It is obtained from \(G\) by replacing each vertex \(x\) of \(G\) by a clique with the number of vertices equal to the degree of \(x\) in \(G\) and replacing each edge between two vertices by an edge joining vertices of these cliques ...

The paired-domination and the upper paired-domination numbers of graphs

open access: yesOpuscula Mathematica, 2015
Summary: 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. The paired-domination number of \(G\), denoted by \(\gamma_{p}(G)\), is the minimum cardinality of a PDS of \(G ...

γ-paired dominating graphs of cycles

open access: yesOpuscula Mathematica, 2022
A paired dominating set of a graph \(G\) is a dominating set whose induced subgraph contains a perfect matching. The paired domination number, denoted by \(\gamma_{pr}(G)\), is the minimum cardinality of a paired dominating set of \(G\). A \(\gamma_{pr}(G)\)-set is a paired dominating set of cardinality \(\gamma_{pr}(G)\).

Total domination versus paired domination [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2012
A dominating set of a graph G is a vertex subset that any vertex of G either belongs to or is adjacent to. A total dominating set is a dominating set whose induced subgraph does not contain isolated vertices. The minimal size of a total dominating set, the total domination number, is denoted by t.

Hot pair-dominated accretion disks

open access: yesThe Astrophysical Journal, 1992
We use a powerful, recently discovered method to determine the structure and to analyze the properties of geometrically thin, steady, hot two-temperature accretion disks, where Comptonized bremsstrahlung is the dominant emission mechanism. The method exploits the fact that the disk solutions depend on two parameters only. This allows all possible local
