摘要
给出了圈C4的St(r+1)—冠的定义,讨论了圈C4的St(r+1)—冠的优美性,用构造性的方法,给出了圈C4的St(r+1)—冠的优美标号。同时,证明了圈C4的St(r+1)—冠是交错图。
This article gives out the definition of St(r+1)—corona of cycle C4,discusses the gracefulness of it,and proposes the graceful labeling of it with constructive method.Furthermore,it proves that the St(r+1)—corona of the cycle C4 is an alternating graph.
