摘要: 1994 年,Mitchem 和Simoson在研究标号图的问题时,提出了超边优美图的概念。在随后的研究中,一些图被证明具有超边优美性质,同时关于超边优美图的一些猜想也被提出。本文利用递归方法构造了蒲公英图的超边优美标号,并证明了蒲公英图是超边优美图。

Abstract: In 1994,Mitchem and Simoson introduced the notion of super edge-graceful graphs when they studied the problem of labeling graph. In the course of subsequent study,it was proven that some graphs were super edge-graceful and some conjections on super edge-graceful graphs were introduced. The super edge-graceful labelings of the dandelion graphs are constructed by recursion,and it is proven that dandelion graphs are super edge-graceful graphs.

Key words: super-edge-graceful, dandelion graph, edge sign matrix
