    Abstract: A graph is called cordial if it has a 0-1 labeling that satisfies certain conditions. A second power of a fan Fn 2 is the join of the null graph N1 and the second power of path Pn2, i.e. Fn2 = N1 + Pn2. In this paper, we study the cordiality of the join and union of pairs of the second power of fans. and give the necessary and sufficient conditions... Show More
