Independent Transversal Total Domination Versus Total Domination in Trees

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A subset of vertices in a graph G is a total dominating set if every vertex in G is adjacent to at least one vertex in this subset. The total domination number of G is the minimum cardinality of any total dominating set in G and is denoted by γt(G).

A Cross-Entropy Approach to the Domination Problem and Its Variants [PDF]

open access: yesEntropy
The domination problem and three of its variants (total domination, 2-domination, and secure domination) are considered. These problems have various real-world applications, including error correction codes, ad hoc routing for wireless networks, and ...

On the domination of triangulated discs [PDF]

open access: yesMathematica Bohemica, 2023
Let $G$ be a $3$-connected triangulated disc of order $n$ with the boundary cycle $C$ of the outer face of $G$. Tokunaga (2013) conjectured that $G$ has a dominating set of cardinality at most $\frac14(n+2)$.

Total double Roman domination in graphs [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2020
Let $G$ be a simple graph with vertex set $V$. A double Roman dominating function (DRDF) on $G$ is a function $f:V\rightarrow\{0,1,2,3\}$ satisfying that if $f(v)=0$, then the vertex $v$ must be adjacent to at least two vertices assigned $2$ or one ...

On the Quasi-Total Roman Domination Number of Graphs

open access: yesMathematics, 2021
Domination theory is a well-established topic in graph theory, as well as one of the most active research areas. Interest in this area is partly explained by its diversity of applications to real-world problems, such as facility location problems ...

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.

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 ...

Total Domination in Generalized Prisms and a New Domination Invariant

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.

Secure Total Domination in Rooted Product Graphs

open access: yesMathematics, 2020
In this article, we obtain general bounds and closed formulas for the secure total domination number of rooted product graphs. The results are expressed in terms of parameters of the factor graphs involved in the rooted product.
