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.

Block Graphs with Large Paired Domination Multisubdivision Number

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.

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 ...

Total and paired domination stability in prisms

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 \(G\).

A Novel Description of Some Concepts in Interval-Valued Intuitionistic Fuzzy Graph with an Application

open access: yesAdvances in Mathematical Physics, 2022
Covering, matching, and domination are the basic concepts in graphs that play a decisive role in the properties of graphs. Calculating these parameters is one of the difficulties in fuzzy graphs when it is not possible to accurately determine the values ...

Heritability and growth analysis of Brant`s oak (Quercus brantii Lindl.) based on sapling characteristics [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2018
Brant`s oak (Quercus brantii Lindl.) is one of the most important tree species of Zagros forests. The major objective of the study was to assess various populations of the species for identification of plus tree individuals and growth trend analysis of ...

The architecture of differences

open access: yesTechne, 2021
Following in the footsteps of the protagonists of the Italian architectural debate is a mark of culture and proactivity. The synthesis deriving from the artistic-humanistic factors, combined with the technical-scientific component, comprises the very ...

Graphs With Large Semipaired Domination Number

open access: yesDiscussiones Mathematicae Graph Theory, 2019
Let G be a graph with vertex set V and no isolated vertices. A sub-set 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

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
