Notes on double Roman domination edge critical graphs

open access: yes
Given a graph G = (V, E), a double Roman dominating function (DRDF) on a graph G is a function f : V → {0, 1, 2, 3} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 3 or two vertices v1
