关于亚完备二分图和r-冠的优美性

On the Gracefulness of Semicomplete Bipartite Graphs and of r- Crowns

本文证明了亚完备二分图、P1+Pn及其r-冠的优美性,由此得到一些有趣的推论和一个有意义的猜想。

In this paper, we show that semicomplete bipartite graphs and the r- Crowns of P1+Pn are both graCeful, We then deduce several interesting Corollaries and propose a meaningful Conjecture.
