Total and paired domination stability in prisms [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2023
Summary: 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 \(G\).

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

Block Graphs with Large Paired Domination Multisubdivision Number [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2021
The paired domination multisubdivision number of a nonempty graph G, denoted by msdpr(G), is the smallest positive integer k such that there exists an edge which must be subdivided k times to increase the paired domination number of 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.

Paired-domination in inflated graphs [PDF]

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 ...

Parameterized Complexity of Paired Domination [PDF]

open access: yes
The Paired Domination problem is one of the well-studied variants of the classical Dominating Set problem. In a graph G on nvertices, a dominating set D (set of vertices such that N[D] = V (G)) is called a paired dominating set of G, if G[D] has perfect matching. In the Paired Domination problem, given a graph G and a positive integer k, the task is to

Distance paired domination numbers of graphs [PDF]

open access: yesDiscrete Mathematics, 2008
Let \(G=(V,E)\) be a graph without an isolated vertex. A set \(D\subset V(G)\) is a dominating set of \(G\) if every vertex in \(V(G)-D\) is adjacent to at least one vertex in \(D\). A set \(D\subset V(G)\) is a paired dominating set of \(G\) if it is dominating and the indiced subgraph \(\) has a perfect matching.

Paired-domination in graphs [PDF]

open access: yes, 2013
D.Phil. (Mathematics) Domination and its variants are now well studied in graph theory. One of these variants, paired-domination, requires that the subgraph induced by the dominating set contains a perfect matching. In this thesis, we further investigate the concept of paired-domination. Chapters 2, 3, 4, and 5 of this thesis have been published in [17]

Paired Domination in Trees

open access: yesGraphs and Combinatorics, 2022
AbstractA set S of vertices in a graph G is a paired dominating set if every vertex of G is adjacent to a vertex in S and the subgraph induced by S contains a perfect matching (not necessarily as an induced subgraph). The paired domination number, $$\gamma _{\mathrm{pr}}(G)$$ γ

All graphs with paired-domination number two less than their order [PDF]

open access: yesOpuscula Mathematica, 2013
Let \(G=(V,E)\) be a graph with no isolated vertices. A set \(S\subseteq V\) is a paired-dominating set of \(G\) if every vertex not in \(S\) is adjacent with some vertex in \(S\) and the subgraph induced by \(S\) contains a perfect matching.
