Perfect edge domination in vague graphs

open access: yesRatio Mathematica, 2021
In this paper, we modified undirected vague graphs and edge domination set based on these two concepts. We study the notions of perfect edge domination, connected perfect edge domination of vague graph. Moreover, we investigate some related properties in

Connected Certified Domination In The Middle Graph Of Certain Graphs [PDF]

open access: yes, 2023
A dominating set S of a graph  is called a certified dominating set of G. If every vertices in S has either zero or at least two neighbours in  A certified dominating set S of G is said to be connected certified dominating set if the subgraph ...

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.

Connected power domination number of product graphs [PDF]

open access: yes, 2022
In this paper, we consider the connected power domination number ($\gamma_{P, c}$) of three standard graph products. The exact value for $\gamma_{P, c}(G\circ H)$ is obtained for any two non-trivial graphs $G$ and $H.$ Further, tight upper bounds are ...

Algorithm and Hardness Results for Outer-connected Dominating Set in Graphs

open access: yesJournal of Graph Algorithms and Applications, 2014
A set D ⊆ V of a graph G = (V,E) is called an outer-connected dominating set of G if for all v ∈ V, |NG[v]∩D| ≥ 1, and the induced subgraph of G on V\D is connected.

[1,2] -Connected domination number of graphs

open access: yes, 2021
  A set  in a graph G is said to be a -connected dominating set if for every vertex ,  and  is connected. The minimum cardinality of a -connected dominating set is called the -connected domination number and is denoted by .

Progress on Roman and Weakly Connected Roman Graphs

open access: yesMathematics, 2021
A graph G for which γR(G)=2γ(G) is the Roman graph, and if γRwc(G)=2γwc(G), then G is the weakly connected Roman graph. In this paper, we show that the decision problem of whether a bipartite graph is Roman is a co-NP-hard problem. Next, we prove similar
