Rainbow Connection Number and Connected Dominating Sets [PDF]
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 ...

Connected cototal domination number of a graph [PDF]
A dominating set $D subseteq V$ of a graph $G = (V,E)$ is said to be a connected cototal dominating set if $langle D rangle$ is connected and $langle V-D rangle neq phi$, contains no isolated vertices.

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

Bridge domination in fuzzy graphs [PDF]
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

The Connected Domination Number of Grids [PDF]
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 Gon alves 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.

The Detour Domination and Connected Detour Domination values of a graph
The number of -sets that belongs to in G is defined as the detour domination value of indicated by for each vertex . In this article, we examined at the concept of a graph’s detour domination value.

Progress on Roman and Weakly Connected Roman Graphs
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

Perfect edge domination in vague graphs
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
