Total dominator total chromatic numbers of cycles and paths

open access: yesRAIRO - Operations Research, 2023
The total dominator total coloring of a graph is a total coloring of the graph such that each object (vertex or edge) of the graph is adjacent or incident to every object of some color class. The minimum number of the color classes of a total dominator total coloring of a graph is called the total dominator total chromatic number of the graph. In (A.P.

Results on the domination number and the total domination number of Lucas cubes

open access: yesArs Mathematica Contemporanea, 2020
Summary: Lucas cubes are the special subgraphs of Fibonacci cubes. For small dimensions, their domination numbers are obtained by direct search or integer linear programming. For larger dimensions some bounds on these numbers are given. In this work, we present the exact values of total domination number of small dimensional Lucas cubes and present ...

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 2-rainbow domination numbers in trees

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A function \(f:V(G) \rightarrow 2^{\{1,2\}}\) is a \(2\)-rainbow dominating function (2RDF) of a graph \(G\) if for every vertex \(v\) with \(f(v) = \emptyset\) we have \(\cup_{u\in N(v)} f(u) = \{1,2\}\). A 2RDF \(f\) is a total 2-rainbow dominating function (T2RDF) if the subgraph induced by the vertices \(v\) with \(f(v) \ne \emptyset\) has no ...

Minus total domination in graphs [PDF]

open access: yes, 2009
For a graph G, let γ(G), γ1(G), i(G) and ir(G) denote the domination, total domination, independent domination and irredundance numbers of G, respectively.

Graphs with Total Domination Number Double of the Matching Number

open access: yesJournal of New Theory
A subset $S$ of vertices of a graph $G$ with no isolated vertex is called a total dominating set of $G$ if each vertex of $G$ has at least one neighbor in the set $S$.

On the inverse signed total domination number in graphs [PDF]

open access: yesOpuscula Mathematica, 2017
In this paper, we study the inverse signed total domination number in graphs and present new sharp lower and upper bounds on this parameter. For example by making use of the classic theorem of Turán (1941), we present a sharp upper bound on \(K_{r+1 ...

On the domination number and the total domination number of Fibonacci cubes

open access: yesArs Mathematica Contemporanea, 2019
Summary: Fibonacci cubes are special subgraphs of the hypercube graphs. Their domination numbers and total domination numbers are obtained for some small dimensions by integer linear programming. For larger dimensions upper and lower bounds on these numbers are given.
