A set D V (G)is the dominating set if every vertex not in D is adjacent to at least one vertex in D.The minimum cadinality of a dominatin set of G is the dominationg number (G).Clearly, for any spanning subgraph H of G, (H) (G). The bondage numberof G, denoted by b(G), is the minimum cardinality of a set of edges B E(G)such that (G − B) > (G), where G − B is the graph with V (G − B) = V (G)and E(G − B) = E(G) \ B.A function f : V (G) {0, 1, 2} is a Roman dominating function if every vertexv for which f(v) = 0 is adjacent to at least one vertex u for which f(u) = 2. Theweight of a Roman dominating function is the value v V (G) f(v). The Romandomination number of a graph G, denoted by R(G), is the minimum weight of aRoman dominating function of G. The Roman bondage number bR(G) of a graph Gis the cardinality of a smallest set of edges B E(G) for which R(G−B) > R(G),where V (G − B) = V (G) and E(G − B) = E(G) \ B.In this paper, for a graph G on a closed surface M, we get an upper bound forthe Roman bondage number bR(G) of G by Euler characteristic (M) of M., 2017年03月, 32, 32, 119,124, 124
