Abstract
Let be any abelian group. A graph G = (V(G), E(G)) is said to be A-cordial[6,9] if there is a mapping f: V(G) A which satisfies the following two conditions with each edge e= uv is labeled as f(u)*f(v), (i) 1, a,b A (ii) 1, a,b A where = the number of vertices with label a = the number of vertices with label b = the number of edges with label a = the number of edges with label b We note that if A = is a multiplicative group. Then the labeling is known as V4 Cordial Labeling. A graph is called a V4 Cordial graph if it admits a V4 Cordial Labeling.In this paper (when n 4(mod 8)), (n<7) are V4 Cordial graphs and Globe Gl(n)(when n 2(mod 4)), (when n 4(mod 8)) and (n≥7) are not V4 Cordial graphs. AMS Mathematics subject classification 2010:05C78.
