英文摘要 | A three-valued function f defined on the vertex set of a graph G = (V, E), f : V --> {1, 0, 1} is a minus dominating function if the sum of its function values over any closed neighborhood is at least one. That is, for every upsilon is an element of V, f (N[upsilon]) greater than or equal to 1, where N[upsilon] consists of upsilon and all vertices adjacent to upsilon. The weight of a minus function is f(V) = Sigma(upsilonis an element ofV) f(upsilon). The minus domination number of a graph G, denoted by gamma(-) (G), equals the minimum weight of a minus dominating function of G. In this paper, sharp lower bounds on minus domination of a bipartite graph are given. Thus, we prove a conjecture proposed by J. Dunbar etc.(Discrete Math. 199(1999) 35-47), and we give a lower bound on gamma(ks) (G) of a graph G. |
