摘要
本文利用几种特殊的标号函数给出一些对称和非对称的优美图,此外还发现所有 p个顶点的树除12棵可规范的树外,都满足泛优美性,这里 p≤10。
In this paper,we give out some symmetric gracful graph and unsymmetric graceful graph by means of some kinds of special numbering function.We also discover that,when p≤10,all of the trees on p vertices satisfy properties of the pan-graceful ex-clusive of 12 normalizable trees.
