Total Domination Versus Paired-Domination in Regular Graphs

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

Characterizations of trees with equal paired and double domination numbers

open access: yesDiscrete Mathematics, 2006
A paired-dominating set of a graph G is a dominating set of vertices whose induced subgraph has a perfect matching, and a double dominating set is a dominating set that dominates every vertex of G at least twice.

Upper total domination versus upper paired-domination

open access: yesQuaestiones Mathematicae, 2007
Let G be a graph with no isolated vertices. A set S of vertices in G is a total dominating set of G if every vertex of G is adjacent to some vertex in S, while a paired-dominating set of G is a dominating set of vertices whose induced subgraph has a ...

γ-paired dominating graphs of cycles [PDF]

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 \(G\).

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.

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)

Total and paired domination numbers of toroidal meshes [PDF]

open access: yesJournal of Combinatorial Optimization, 2012
Let $G$ be a graph without isolated vertices. The total domination number of $G$ is the minimum number of vertices that can dominate all vertices in $G$, and the paired domination number of $G$ is the minimum number of vertices in a dominating set whose induced subgraph contains a perfect matching.

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.
