A. Bahremandpour, Fu-Tao Hu, S. M. Sheikholeslami +1

A Roman dominating function on a graph $G = (V, E)$ is a function $f : V \to {0, 1, 2}$ such that every vertex $v \in V$ with $f (v) = 0$ has at least one neighbor $u \in V$ with $f(u)…

Roman Bondage Number of a Graph

Fu-Tao Hu, Jun-Ming Xu

The Roman dominating function on a graph $G = (V, E)$ is a function $f : V \to {0, 1, 2}$ such that each vertex $x$ with $f (x) = 0$ is adjacent to at least one vertex $y$ with $f(y…
