Domination Number, Independent Domination Number and 2-Independence Number in Trees
For a graph G, let γ(G) be the domination number, i(G) be the independent domination number and β2(G) be the 2-independence number. In this paper, we prove that for any tree T of order n ≥ 2, 4β2(T) − 3γ(T) ≥ 3i(T), and we characterize all trees ...

Maker-Breaker domination number [PDF]
The Maker-Breaker domination game is played on a graph $G$ by Dominator and Staller. The players alternatively select a vertex of $G$ that was not yet chosen in the course of the game.

Graphs with equal domination and independent domination numbers [PDF]
Let γ(G) and i(G) denote the domination number and independent domination number of a graph G. In this article, we establish a sufficient condition for a graph G to satisfy which yields some of the well known classical theorems as corollaries.

Independent [1,2]-number versus independent domination number [PDF]
A [1; 2]-set S in a graph G is a vertex subset such that every vertex not in S has at least one and at most two neighbors in it. If the additional requirement that the set be independent is added, the existence of such sets is not guaranteed in every ...

On the equality of domination number and 2-domination number
The 2-domination number $ _2(G)$ of a graph $G$ is the minimum cardinality of a set $ D \subseteq V(G) $ for which every vertex outside $ D $ is adjacent to at least two vertices in $ D $. Clearly, $ _2(G) $ cannot be smaller than the domination number $ (G) $. We consider a large class of graphs and characterize those members which satisfy $ _2=

Bounds on the Locating-Domination Number and Differentiating-Total Domination Number in Trees
A subset S of vertices in a graph G = (V,E) is a dominating set of G if every vertex in V − S has a neighbor in S, and is a total dominating set if every vertex in V has a neighbor in S.

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

Medium Domination Decomposition of Graphs
A set of vertices in a graph dominates if every vertex in is either in or adjacent to a vertex in . The size of any smallest dominating set is called domination number of .
