CORDIAL LABELING FOR FIVE STAR GRAPH

In this paper, we proved that the five star graph $K_{1,{\eta_1}}$ $ \wedge K_{1,{\eta_2}}$ $ \wedge K_{1, {\eta_3}} $ $ \wedge K_{1,{\eta_4}} $ $\wedge K_{1,{\eta_5}}$ is a cordial graph for all ${\eta_1} \geq 1, {\eta_2} \geq 1, {\eta_3} \geq 1, {\eta_4} \geq 1$ and ${\eta_5} \geq 1$.
