Abstract

Let G(V, E) be a finite connected simple graph. A function  ¦ : V(G) ® {-1,1} is a signed dominating function if for every vertex vÎV(G), the closed neighborhood of  v contains more vertices with function values 1 than with -1. The signed domination number gs(G) of G is the minimum weight of a signed dominating function on G. In this paper, we calculate the signed domination numbers of the Cartesian product of two paths P­m and Pn for m= 8 and arbitrary n.
