Title A name given to the resource Roman domination in signed graphs Subject The topic of the resource Dominating functions; Roman dominating functions; Signed graphs Description An account of the resource Let S = (G, ?) be a signed graph. A function f : V ? {0, 1, 2} is a Roman dominating function on S if (i) for each v ? V, f(N[v]) = f(v) + Pu?N(v) ?(uv)f(u) ? 1 and (ii) for each vertex v with f(v) = 0, there exists a vertex u ? N+(v) such that f(u) = 2. In this paper we initiate a study on Roman dominating function on signed graphs. We characterise the signed paths, cycles and stars that admit a Roman dominating function. 2023 Azarbaijan Shahid Madani University.
