In answer to the open questions proposed by Henning and Slater, we give sharp upper bounds on the upper signed domination number of a regular graph and on the signed domination number of a connected cubic graph. Let G = (V, E) be a simple graph. For v E V, we denote by d(u) the degree of v in V, by
An e cient minus (respectively, signed) dominating function of a graph G = (V; E) is a function f : The e cient minus (respectively, signed) domination problem is to ΓΏnd an e cient minus (respectively, signed) dominating function of G. In this paper, we show that the e cient minus (respectively, si
