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-

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

Domination versus edge domination [PDF]

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

Domination Reliability [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
In this paper, we propose a new network reliability measure for some particular kind of service networks, which we refer to as domination reliability. We relate this new reliability measure to the domination polynomial of a graph and the coverage probability of a hypergraph.

Homes as ‘cages of violence’ during the COVID-19 pandemic: A pastoral care approach to the case of Botswana

open access: yesHTS Teologiese Studies/Theological Studies, 2022
Violence has become a common phenomenon that affects women and children, particularly during the coronavirus disease 2019 (COVID-19) pandemic. While the lockdown regulations were meant to save lives by preventing further spread of the virus, another ...

Relating domination, exponential domination, and porous exponential domination

open access: yesDiscrete Optimization, 2017
The domination number $ (G)$ of a graph $G$, its exponential domination number $ _e(G)$, and its porous exponential domination number $ _e^*(G)$ satisfy $ _e^*(G)\leq _e(G)\leq (G)$. We contribute results about the gaps in these inequalities as well as the graphs for which some of the inequalities hold with equality.

Graphs with equal domination and certified domination numbers [PDF]

open access: yesOpuscula Mathematica, 2019
A set \(D\) of vertices of a graph \(G=(V_G,E_G)\) is a dominating set of \(G\) if every vertex in \(V_G-D\) is adjacent to at least one vertex in \(D\). The domination number (upper domination number, respectively) of \(G\), denoted by \(\gamma(G)\) (\(\

Dominating vertex covers: the vertex-edge domination problem [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A variant of domination, namely, vertex-edge domination in which a set of vertices dominating the edges is studied. The vertex-edge domination number of a graph \(G\), \(\gamma_{\mathrm{ve}}(G)\), is defined to be the cardinality of a smallest set \(D\) such that there exists a vertex cover \(C\) of \(G\) such that each vertex in \(C\) is dominated by ...

Secrétaires et policiers ? Les assistant·es d’éducation et leurs appropriations d’un travail dominé

open access: yesLa Nouvelle Revue du Travail, 2022
The article highlights the dominated position that French secondary school supervisors assume in the division of educational work. It does this by analysing the content of their tasks as well as the different ways in which they appropriate it ...
