Italian Domination and Perfect Italian Domination on Sierpinski Graphs

Jismy Varghese, Anu V, Aparna Lakshmanan S

An Italian dominating function (IDF) of a graph G is a function $f : V (G) \to {0, 1, 2}$ satisfying the condition that for every $v \in V$ with $f (v) = 0$ , $\sum_{ u\in…

Impact of Some Graph Operations on Double Roman Domination Number

Anu V., Aparna Lakshmanan S.

Given a graph $G = (V, E)$ , a function $f : V \to {0, 1, 2, 3}$ having the property that if $f (v) = 0$ , then there exist $v_{1}, v_{2} \in N (v)$ such that $f (v_{1}) = f (v_{2}) = 2$ or th…

On the Double Roman Domination Number of Generalized Sierpinski Graphs

Anu V., Aparna Lakshmanan S.

In this paper, we study the double Roman domination number of generalized Sierpiński graphs $S (G, t)$ . More precisely, we obtain a bound for the double Roman domination number of $S…
