A note on total domination [PDF]

open access: yesDiscrete Mathematics, 1984
A dominating [totally dominating] set is a subset D of the vertex set V(G) of a graph G with the property that for each \(x\in V(G)\setminus D\) [for each \(x\in V(G)]\) there exists \(y\in D\) adjacent to x. The domination number \(\gamma\) (G) [the total domination number \(\gamma_ t(G)]\) of G is the minimum number of vertices of a dominating ...

Total Domination in Generalized Prisms and a New Domination Invariant [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2021
In this paper we complement recent studies on the total domination of prisms by considering generalized prisms, i.e., Cartesian products of an arbitrary graph and a complete graph.

Total domination versus paired domination [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2012
A dominating set of a graph G is a vertex subset that any vertex of G either belongs to or is adjacent to. A total dominating set is a dominating set whose induced subgraph does not contain isolated vertices. The minimal size of a total dominating set, the total domination number, is denoted by t.

Total Domination Multisubdivision Number of a Graph [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2015
The domination multisubdivision number of a nonempty graph G was defined in [3] as the minimum positive integer k such that there exists an edge which must be subdivided k times to increase the domination number of G.

Partial Total Domination in Hypergraphs [PDF]

open access: yesMathematics
This paper establishes fundamental results for partial total domination in hypergraphs. We present tight bounds for the partial total domination number in k-uniform hypergraphs, demonstrate relationships with classical domination parameters, and provide ...

Total connected domination game [PDF]

open access: yesOpuscula Mathematica, 2021
The (total) connected domination game on a graph \(G\) is played by two players, Dominator and Staller, according to the standard (total) domination game with the additional requirement that at each stage of the game the selected vertices induce a ...

Neighbourhood total domination in graphs [PDF]

open access: yesOpuscula Mathematica, 2011
Let \(G = (V,E)\) be a graph without isolated vertices. A dominating set \(S\) of \(G\) is called a neighbourhood total dominating set (ntd-set) if the induced subgraph \(\langle N(S)\rangle\) has no isolated vertices.

On upper bounds for total $k$-domination number via the probabilistic method [PDF]

open access: yes, 2023
summary:For a fixed positive integer $k$ and $G=(V, E)$ a connected graph of order $n$, whose minimum vertex degree is at least $k$, a set $S\subseteq V$ is a total $k$-dominating set, also known as a $k$-tuple total dominating set, if every vertex $v\in

Total mixed domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
For a graph [Formula: see text] we call a subset [Formula: see text] a total mixed dominating set of G if each element of [Formula: see text] is either adjacent or incident to an element of S, and the total mixed domination number of G is the minimum ...

Strong total domination and weak total domination in Mycielski’s graphs

open access: yesMalaya Journal of Matematik, 2020
Let \(G=(V, E)\) be a graph. A set \(S \subseteq V\) is called a weak total dominating set (WTD-set) if each vertex \(v \in V-S\) is adjacent to a vertex \(u \in S\) with \(\operatorname{deg}(v)>\operatorname{deg}(u)\) and every vertex in \(S\) adjacent to a vertex in \(S\).
