摘要

The Normal product G_1 o G_2 of two graphs G_1 (V_1, E_1) and G_2(V_2, E_2) is the graph with the vertex set V(G_1) × V(G_2) and edges consisting of those pairs of vertices (u_1, v_1) and (u_2, v_2) if and only if one of the following three conditions are satisfied, (ⅰ)u_1= u _2 and v_1 v_2 ∈ E_2 (ⅱ) v_1 = v_2 and u_1u_2 ∈ E_1 (ⅲ) u_1u_2 ∈ E_1 and v_1 v_2 ∈ E_2. In this paper we study Normal product for certain class of graphs and prove some interesting results.
