Connected domination critical graphs

open access: yesApplied Mathematics Letters, 2004
A dominating set in a graph G is a connected dominating set of G if it induces a connected subgraph of G. The minimum number of vertices in a connected dominating set of G is called the connected domination number of G, and is denoted by γc(G).

The Domination Parameters on a kind of the regular honeycomb structure [PDF]

open access: yesComputer Science Journal of Moldova, 2022
The honeycomb mesh, based on hexagonal structure, has enormous applications in chemistry and engineering. A major challenge in this field is to understand the unique properties of honeycomb structures, which depend on their properties of topology. One

The Connected Domination Number of Grids [PDF]

open access: yes, 2021
Closed form expressions for the domination number of an $n \times m$ grid have attracted significant attention, and an exact expression has been obtained in 2011 by Gonçalves et al. In this paper, we present our results on obtaining new lower bounds on the connected domination number of an $n \times m$ grid.

Rainbow Connection Number and Connected Dominating Sets [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2011
AbstractThe rainbow connection number of a connected graph is the minimum number of colors needed to color its edges, so that every pair of its vertices is connected by at least one path in which no two edges are colored the same. In this article we show that for every connected graph on n vertices with minimum degree δ, the rainbow connection number ...

Enumerating Connected Dominating Sets

open access: yesCoRR, 2022
The question to enumerate all inclusion-minimal connected dominating sets in a graph of order $n$ in time significantly less than $2^n$ is an open question that was asked in many places. We answer this question affirmatively, by providing an enumeration algorithm that runs in time $\mathcal{O}(1.9896^n)$, using polynomial space only.

Bridge domination in fuzzy graphs [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2023
In communication networks, strong connectivity between nodes is critical. The failure of strong connectivity between nodes may jeopardize the network’s stability. In fuzzy graphs, various dominating sets using strong edges are identified to avoid network

Connected End Anti-Fuzzy Equitable Dominating Set In Anti-Fuzzy Graphs

open access: yesRatio Mathematica, 2023
In this paper, the notion of connected end anti-fuzzy equitable dominating set of an anti-fuzzy graph is discussed. The connected end anti-fuzzy equitable domination number for some standard graphs are obtained.

Connected Dominating Sets in Triangulations

open access: yesCoRR, 2023
We show that every $n$-vertex triangulation has a connected dominating set of size at most $10n/21$. Equivalently, every $n$ vertex triangulation has a spanning tree with at least $11n/21$ leaves. Prior to the current work, the best known bounds were $n/2$, which follows from work of Albertson, Berman, Hutchinson, and Thomassen (J. Graph Theory \textbf{

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.
