图C_n·P_3的优美标号与调和标号

Graceful and Harmonious Labelings of Graph C_n · P_3

设C_n·P_3(n≥3)是由圈C_n上一点与路P_3的起点粘合而得到的图。本文研究图C_n·P_3的优美标号与调和标号,得到一些结果。

Let Cn · P3( n ≥ 3) be a graph that the cycle Cn joins with path P3 in start vertex of P3 . In this paper graceful and harmonious labelings of Cn · P3 is studied. Some results arc given.
