The least eigenvalue of signless Laplacian of non-bipartite graphs with given domination number

open access: yes, 2014
Let $G$ be a connected non-bipartite graph on $n$ vertices with domination number $\gamma \le \frac{n+1}{3}$. We investigate the least eigenvalue of the signless Laplacian of $G$, and present a lower bound for such eigenvalue in terms of the domination ...

[1,2]-Complementary connected domination number of graphs-III

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2019
\(S\subset V(G)\) is a $[1,2]$-complementary connected dominating set of a graph \(G\) if each \(v\in V(G)\setminus S\) has one or two neighbors in \(S\) and \(G\setminus S\) is connected. The paper discusses cubic graphs of order \(12\) whose smallest $ [1,2]$-complementary connected dominating sets have cardinality \(3\).

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 ...

Forcing Parameters in Fully Connected Cubic Networks

open access: yesMathematics, 2022
Domination in graphs has been extensively studied and adopted in many real life applications. The monitoring electrical power system is a variant of a domination problem called power domination problem.

Weakly connected domination subdivision numbers

open access: yesDiscussiones Mathematicae Graph Theory, 2008
A set D of vertices in a graph G = (V, E) is a weakly connected dominating set of G if D is dominating in G and the subgraph weakly induced by D is connected. The weakly connected domination number of G is the minimum cardinality of a weakly connected dominating set of G.

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.

Upper bounds for domination related parameters in graphs on surfaces

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
In this paper we give tight upper bounds on the total domination number, the weakly connected domination number and the connected domination number of a graph in terms of order and Euler characteristic.

Total mixed domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
For a graph [Formula: see text] we call a subset [Formula: see text] a total mixed dominating set of G if each element of [Formula: see text] is either adjacent or incident to an element of S, and the total mixed domination number of G is the minimum ...
