Double outer-independent domination number of graphs

open access: yes, 2022
Let G be a graph with no isolated vertex. A set D ⊆ V (G) is a double outer-independent dominating set of G if V (G)\D is an independent set and |N[v]∩D| ≥ 2 for every v ∈ V (G), where N[v] denotes the closed neighbourhood of v.

On average lower independence and domination numbers in graphs

open access: yesDiscrete Mathematics, 2005
Let \(V(G)\) be the vertex set of a graph \(G\). The lower independence number \(i_{av}(G)\) of a graph \(G\) is defined as \(\frac{1}{| V(G)| }\sum_{v\in V(G)}i_v(G)\), and the average lower domination number \({\gamma}_{av}(G)\) is defined as \(\frac{1}{| V(G)| }\sum_{v\in V(G)}{\gamma}_v(G)\), where \(i_v(G)\) is the minimum cardinality of a maximal

Variants of the Domination Number for Flower Snarks [PDF]

open access: yes, 2023
We consider the flower snarks, a widely studied infinite family of 3--regular graphs. For the Flower snark $J_n$ on $4n$ vertices, it is trivial to show that the domination number of $J_n$ is equal to $n$. However, results are more difficult to determine

Domination and Independent Domination in Hexagonal Systems

open access: yes, 2021
A vertex subset D of G is a dominating set if every vertex in V(G)\D is adjacent to a vertex in D. A dominating set D is independent if G[D], the subgraph of G induced by D, contains no edge.

On independent domination and packing numbers of subcubic graphs

open access: yesApplied Mathematics and Computation
In a recent paper, Cho and Kim proved that in subcubic graphs, the independent domination number is at most three times the packing number. They subsequently posed the question of characterizing subcubic graphs that achieve this bound. In this paper, we completely solve the question by proving that exactly four graphs meet this bound.

Product throttling for power domination [PDF]

open access: yes, 2023
The product power throttling number of a graph is defined to study product throttling for power domination. The domination number of a graph is an upper bound for its product power throttling number.
