Effect of vertex deletion on the weak Roman domination number of a graph
Let be a graph and be a function. The weight of a vertex is and a vertex with weight is said to be undefended with respect to , if it is not adjacent to a vertex with positive weight. The function is a weak Roman dominating function (WRDF) if each vertex with is adjacent to a vertex with such that t...
