摘要: 用构造的方法给出图K4-P(n,2),K3-P(n,2)和I(K1,1,n)的优美标号, 并证明了图K4-P(n,2),K3-P(n,2)和I(K1,1,n)都是优美图.

关键词: 优美图, 完全三部图, 优美标号,

Abstract: We prove that  K4-P(n,2),K3-P(n,2) and I(K1,1,n) are graceful graphs by using the constructive method, which
gives the  graceful labeling of graphs K4-P(n,2),K3-P(n,2) and I(K1,1,n).

Key words: graceful labeling, corona, graceful graph, complete tripartite graph
