On the signed domination number of some Cayley graphs

Saeid Alikhani, Fatemeh Ramezani, Ebrahim Vatandoost

A signed dominating function of graph $Γ$ is a function $g : V (Γ) ⟶ {- 1, 1}$ such that $\sum_{u \in N [v]} g (u) > 0$ for each $v \in V (Γ)$ . The signed domination number…

On the Roman domination number of generalized Sierpinski graphs

Fatemeh Ramezani, Erick D. Rodriguez-Bazan, Juan A. Rodriguez-Velazquez

A map $f : V \to {0, 1, 2}$ is a Roman dominating function on a graph $G = (V, E)$ if for every vertex $v \in V$ with $f (v) = 0$ , there exists a vertex $u$ , adjacent to $v$ ,…
