Complexity of Paired Domination in AT-free and Planar Graphs [PDF]

open access: yesSSRN Electronic Journal, 2022
For a graph $G=(V,E)$, a subset $D$ of vertex set $V$, is a dominating set of $G$ if every vertex not in $D$ is adjacent to atleast one vertex of $D$. A dominating set $D$ of a graph $G$ with no isolated vertices is called a paired dominating set (PD-set), if $G[D]$, the subgraph induced by $D$ in $G$ has a perfect matching. The Min-PD problem requires

Paired domination stability in graphs

open access: yesArs Mathematica Contemporanea, 2022
Summary: A 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, \(\gamma_{\mathrm{pr}} (G)\), of \(G\) is the minimum cardinality of a paired ...

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.

Unique Minimum Semipaired Dominating Sets in Trees

open access: yesDiscussiones Mathematicae Graph Theory, 2023
Let G be a graph with vertex set V. A subset S ⊆ V is a semipaired dominating set of G if every vertex in V \ S is adjacent to a vertex in S and S can be partitioned into two element subsets such that the vertices in each subset are at most distance two ...

Results of Paired Domination of Some Special Graph Families on Transformation Graphs: $G^{xy+}$ and $G^{xy-}$

open access: yesJournal of New Theory, 2023
In this study, transformation graphs obtained from the concept of the total graph and the result of its paired domination number for some special graph families are discussed.

Equitable and Paired Equitable Domination in Inflated Graphs and Their Complements

open access: yesAxioms, 2023
Domination plays an indispensable role in graph theory. Various types of domination explore various types of applications. Equal-status people work together and interlace with each other easily.

Edge subdivision and edge multisubdivision versus some domination related parameters in generalized corona graphs [PDF]

open access: yesOpuscula Mathematica, 2016
Given a graph \(G=(V,E)\), the subdivision of an edge \(e=uv\in E(G)\) means the substitution of the edge \(e\) by a vertex \(x\) and the new edges \(ux\) and \(xv\).

γ-Paired dominating graphs of lollipop, umbrella and coconut graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2023
A paired dominating set of a graph G is a dominating set whose induced subgraph has a perfect matching. The paired domination number γpr(G) of G is the minimum cardinality of a paired dominating set. A paired dominating set D is a γpr(G)-set if |D|=γpr(G)

Neighbourhood total domination in graphs [PDF]

open access: yesOpuscula Mathematica, 2011
Let \(G = (V,E)\) be a graph without isolated vertices. A dominating set \(S\) of \(G\) is called a neighbourhood total dominating set (ntd-set) if the induced subgraph \(\langle N(S)\rangle\) has no isolated vertices.

Paired-domination

open access: yesDiscussiones Mathematicae Graph Theory, 1998
It is known that a dominating set \(S\) of vertices of a graph \(G\) is a set such that every vertex of \(G\) is either in \(S\) or adjacent to at least one member of \(S\). A paired-dominating set is a dominating set whose induced subgraph contains at least one perfect matching.
