New Bounds on the Double Total Domination Number of Graphs

open access: yesBulletin of the Malaysian Mathematical Sciences Society, 2021
Let G be a graph of minimum degree at least two. A set $$D\subseteq V(G)$$ D ⊆ V ( G ) is said to be a double total dominating set of G if $$|N(v)\cap D|\ge 2$$ | N ( v ) ∩ D | ≥ 2 for every vertex $$v\in V(G)$$ v ∈ V ( G ) .

Stability of Domination in Graphs

open access: yesRatio Mathematica, 2023
The stability of dominating sets in Graphs is introduced and studied, in this paper. Here D is a dominating set of Graph G. In this paper the vertices of D and vertices of $V - D$ are called donors and acceptors respectively.

Closed formulas for the total Roman domination number of lexicographic product graphs

open access: yesArs Math. Contemp., 2021
Let G be a graph with no isolated vertex and f :  V ( G ) → {0, 1, 2} a function. Let V i  = { x  ∈  V ( G ) : f ( x ) = i } for every i  ∈ {0, 1, 2} . We say that f is a total Roman dominating function on G if every vertex in V 0 is adjacent to at least

On the Paired-Domination Subdivision Number of Trees

open access: yesMathematics, 2021
A paired-dominating set of a graph G without isolated vertices is a dominating set of vertices whose induced subgraph has perfect matching. The minimum cardinality of a paired-dominating set of G is called the paired-domination number γpr(G) of G.

On domination multisubdivision number of unicyclic graphs [PDF]

open access: yesOpuscula Mathematica, 2018
The paper continues the interesting study of the domination subdivision number and the domination multisubdivision number. On the basis of the constructive characterization of the trees with the domination subdivision number equal to 3 given in [H. Aram,

Characterization of outerplanar graphs with equal 2-domination and domination numbers

open access: yesTheory and Applications of Graphs, 2022
A {\em $k$-domination number} of a graph $G$ is minimum cardinality of a $k$-dominating set of $G$, where a subset $S \subseteq V(G)$ is a {\em $k$-dominating set} if each vertex $v\in V(G)\setminus S$ is adjacent to at least $k$ vertices in $S$.

Resolving independent domination number of some special graphs

open access: yes, 2021
Dominating set is a set D of vertices of graph G(V, E) and every vertex u ∈ V(G) − D is adjacent to some vertex υ ∈ D. The set D is called independent set if no two vertices in D are adjacent. Independent domination number of G is the minimum cardinality
