Anarchism and non-domination [PDF]

open access: yes, 2019
In this article we recover the classical anarchist deployment of republican tropes of non-domination, tyranny and slavery, to expose the conservative limits of the contemporary neo-Roman republican revival. For the anarchists, the modern nation state and

DOMINATION AND EDGE DOMINATION IN TREES [PDF]

open access: yesUral Mathematical Journal, 2020
Let \(G=(V,E)\) be a simple graph. A set \(S\subseteq V\) is a dominating set if every vertex in \(V \setminus S\) is adjacent to a vertex in \(S\).

Domination, Eternal Domination, and Clique Covering

open access: yesDiscussiones Mathematicae Graph Theory, 2015
Eternal and m-eternal domination are concerned with using mobile guards to protect a graph against infinite sequences of attacks at vertices. Eternal domination allows one guard to move per attack, whereas more than one guard may move per attack in the m-

On Domination in Graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2005
Summary: For a finite undirected graph \(G\) on \(n\) vertices two continuous optimization problems taken over the \(n\)-dimensional cube are presented and it is proved that their optimum values equal the domination number \(\gamma\) of \(G\). An efficient approximation method is developed and known upper bounds on \(\gamma\) are slightly improved.

On domination and independent domination numbers of a graph [PDF]

open access: yesDiscrete Mathematics, 1978
AbstractFor a graph G, the definitions of domination number, denoted γ(G), and independent domination number, denoted i(G), are given, and the following results are obtained:Theorem. If G does not have an induced subgraph isomorphic to K1,3, then γ(G) = i(G).Corollary 1. For any graph G, γ(L(G))=i(L(G)), where L(G) is the line graph of G. (This extends

Relating 2-Rainbow Domination To Roman Domination

open access: yesDiscussiones Mathematicae Graph Theory, 2017
For a graph G, let R(G) and yr2(G) denote the Roman domination number of G and the 2-rainbow domination number of G, respectively. It is known that yr2(G) ≤ R(G) ≤ 3/2yr2(G). Fujita and Furuya [Difference between 2-rainbow domination and Roman domination

Upper paired domination versus upper domination [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
A paired dominating set $P$ is a dominating set with the additional property that $P$ has a perfect matching. While the maximum cardainality of a minimal dominating set in a graph $G$ is called the upper domination number of $G$, denoted by $\Gamma(G ...

Domination versus edge domination [PDF]

open access: yesDiscrete Applied Mathematics, 2020
We propose the conjecture that the domination number $γ(G)$ of a $Δ$-regular graph $G$ with $Δ\geq 1$ is always at most its edge domination number $γ_e(G)$, which coincides with the domination number of its line graph. We prove that $γ(G)\leq \left(1+\frac{2(Δ-1)}{Δ2^Δ}\right)γ_e(G)$ for general $Δ\geq 1$, and $γ(G)\leq \left(\frac{7}{6}-\frac{1}{204 ...

Degree equitable restrained double domination in graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2021
A subset D ⊆ V(G) is called an equitable dominating set of a graph G if every vertex v ∈ V(G) \ D has a neighbor u ∈ D such that |dG(u)-dG(v)| ≤ 1. An equitable dominating set D is a degree equitable restrained double dominating set (DERD-dominating set)
