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 ...

Total and paired domination stability in prisms [PDF]

open access: yes, 2023
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 ...

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 ...

Triple Connected Domination Number of a Graph [PDF]

open access: yes, 2012
The concept of triple connected graphs with real life application was introduced by considering the existence of a path containing any three vertices of a graph G.

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.

Paired-domination game played in graphs [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2019
In this paper, we continue the study of the domination game in graphs introduced by Bre{\v{s}}ar, Klav{\v{z}}ar, and Rall [SIAM J. Discrete Math. 24 (2010) 979--991].

Paired Domination in Graphs

open access: yes, 2020
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).
