Revisiting $k$ -tuple dominating sets with emphasis on small values of $k$

Babak Samadi, Nasrin Soltankhah, Doost Ali Mojdeh

For any graph $G$ of order $n$ with degree sequence $d_{1} \geq \dots \geq d_{n}$ , we define the double Slater number $s ℓ_{\times 2} (G)$ as the smallest integer $t$ such that $t+d_…

Restrained condition on double Roman dominating functions

Babak Samadi, Nasrin Soltankhah, H. Abdollahzadeh Ahangar +4

We continue the study of restrained double Roman domination in graphs. For a graph $G=\big{(}V(G),E(G)\big{)}$, a double Roman dominating function $f$ is called a restrained double…

Restrained Italian domination in graphs

Babak Samadi, Morteza Alishahi, Iman Masoumi +1

For a graph $G = (V (G), E (G))$ , an Italian dominating function (ID function) $f : V (G) \to {0, 1, 2}$ has the property that for every vertex $v \in V (G)$ with $f (v) = 0$ , either $v$ …

Covering Italian domination in graphs

Abdollah Khodkar, Doost Ali Mojdeh, Babak Samadi +1

For a graph $G = (V (G), E (G))$ , an Italian dominating function (ID function) of $G$ is a function $f : V (G) \to {0, 1, 2}$ such that for each vertex $v \in V (G)$ with $f (v) = 0$ , $f…

The Laplacian eigenvalue 2 of bicyclic graphs

Doost Ali Mojdeh, Mohammad Habibi, Masoumeh Farkhondeh

If $G$ is a graph, its Laplacian is the difference between diagonal matrix of its vertex degrees and its adjacency matrix. A one-edge connection of two graphs $G_{1}$ and $G_{2}$ i…

Double domination and total $2$ -domination in digraphs and their dual problems

Doost Ali Mojdeh, Babak Samadi

A subset $S$ of vertices of a digraph $D$ is a double dominating set (total $2$ -dominating set) if every vertex not in $S$ is adjacent from at least two vertices in $S$ , and every…
