Singed Total Domatic Number of a Graph [PDF]

open access: yes, 2010
The maximum number of functions in a signed total dominating family on G is the signed total domatic number of G. In this paper, some properties related signed total domatic number and signed total domination number of a graph are studied and found the ...

Nonsplit Neighbourhood Tree Domination Number In Connected Graphs

open access: yes, 2021
: Let G = (V, E) be a connected graph. A subset D of V is called a dominating set of G if N[D] = V. The minimum cardinality of a dominating set of G is called the domination number of G and is denoted by g(G).

Algorithmic approach, mathematical modelling and network applications of connected certified domination in graphs: A comprehensive review [PDF]

open access: yesEPJ Web of Conferences
In this study we have reviewed a very important variant of graph domination theory that is connected certified domination (CCD) and also presents CCD as graph-based model for network optimization.

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 ...

Alternative Domination in Graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
Sometimes while you are using the Internet, for example, via a Wi-Fi network from one of the companies, the Internet is suddenly cut off due to a malfunction at that point, which disrupts your important work on the Internet, so there is a need for ...

Weakly convex and convex domination numbers [PDF]

open access: yesOpuscula Mathematica, 2004
Two new domination parameters for a connected graph \(G\): the weakly convex domination number of \(G\) and the convex domination number of \(G\) are introduced. Relations between these parameters and the other domination parameters are derived.

On connected k-domination numbers of graphs

open access: yesDiscrete Mathematics, 2004
A subset \(D\) of the vertex set \(V\) of a graph \(G\) is called a connected \(k\)-dominating set (for a positive integer \(k)\) in \(G\), if for each vertex \(x\in V-D\) there exists a vertex \(y\in D\) such that the distance between \(x\) and \(y\) in \(G\) is at most \(k\) and moreover the subgraph \(G[D]\) of \(G\) induced by \(D\) is conneced ...
