摘要
Given a graph G and a set S⊆ V(G) a vertex v is said to be 3 -dominated by a vertex w in S if either v=w, or v∉ S and there exists a vertex u in V(G)-S such that P:wuv is a path in G. A set S⊆ V(G)is an 3 -dominating set of G if every vertex v is 3 -dominated by a vertex w in S.The 3 -domination number of G, denoted by γ F3(G), is the minimum cardinality of an 3 -dominating set of G. In this paper, we study the 3 -domination of Cartesian product of graphs, and give formulas to compute the 3 -domination number of Pm×Pnand Pm× Cnfor special m,n.
