Product Cordial Labeling of Line Graph of Some Graphs


S. K. Vaidya, C. M. Barasara




The line graph $L(G)$ of a graph $G$ is the graph whose vertex set is $E(G)$ and two vertices are adjacent in $L(G)$ whenever they are incident in $G$. In this paper we have investigated product cordial labeling of line graph of some product cordial graphs.
