Proper 3-Dominating Sets in Graphs

open access: yesMathematics
A dominating set is a classic concept that is widely used in road safety, disaster rescue operations, and chemical graphs. In this paper, we introduce a variation of the dominating set: the proper 3-dominating set.

False alarms in fault-tolerant dominating sets in graphs [PDF]

open access: yesOpuscula Mathematica, 2012
We develop the problem of fault-tolerant dominating sets (liar's dominating sets) in graphs. Namely, we consider a new kind of fault - a false alarm.

Independent Dominating Set on Chain of Fuzzy Graphs

open access: yesTikrit Journal of Pure Science, 2023
             In this paper, we applied some properties on chain fuzzy graphs, which comprise vertex identification. These properties are independent sets and independent dominant sets.

Locating-dominating sets in hypergraphs [PDF]

open access: yesPeriodica Mathematica Hungarica, 2016
A hypergraph is a generalization of a graph where edges can connect any number of vertices. In this paper, we extend the study of locating-dominating sets to hypergraphs. Along with some basic results, sharp bounds for the location-domination number of hypergraphs in general and exact values with specified conditions are investigated.

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Dominating Vertex Covers: The Vertex-Edge Domination Problem

open access: yesDiscussiones Mathematicae Graph Theory, 2021
The vertex-edge domination number of a graph, γve(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 a vertex in D.

Results on Relatively Prime Domination Number of Vertex Switching of Some Graphs

open access: yesRatio Mathematica, 2023
If a set S ⊆ V has at least two members and every pair of vertices u and v is such that (d(u), d(v)) = 1, then it is said to be a relatively prime dominating set.

Power domination in maximal planar graphs [PDF]

open access: yes, 2019
Power domination in graphs emerged from the problem of monitoring an electrical system by placing as few measurement devices in the system as possible. It corresponds to a variant of domination that includes the possibility of propagation.

Dominating sets in plane triangulations

open access: yesDiscrete Mathematics, 2010
In 1996, Matheson and Tarjan conjectured that any n-vertex triangulation with n sufficiently large has a dominating set of size at most n/4. We prove this for graphs of maximum degree 6.

Approximating k-Connected m-Dominating Sets [PDF]

open access: yesAlgorithmica, 2022
A subset $S$ of nodes in a graph $G$ is a $k$-connected $m$-dominating set ($(k,m)$-cds) if the subgraph $G[S]$ induced by $S$ is $k$-connected and every $v \in V \setminus S$ has at least $m$ neighbors in $S$. In the $k$-Connected $m$-Dominating Set ($(k,m)$-CDS) problem the goal is to find a minimum weight $(k,m)$-cds in a node-weighted graph. For $m
