摘要
研究非连通图3C8m∪C8m-1∪G的优美性.证明如下结论:对任意正整数m,若图G是特征为k且缺标号值k+24m-2的交错图,则非连通图3C8m∪C8m-1∪G存在缺标号值k+1的优美标号.
The gracefulness of the unconnected graph 3C8m∪C8m-1∪G is studied. It is proved that, for any positive integer m, if G is an alternating graph whose feature is k and G lacks labeling number k＋24m-2, then 3C8m∪C8m-1∪G has graceful labeling that lacks labeling number k＋ 1.
