A Note on Roman Domination of Digraphs

A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of a digraph D, denoted by γ(D), is the minimum cardinality of a dominating set of D. A Roman dominating function (RDF) on a digraph D is a funct...
