The K-Gracefulness of the Cornonal of Complete Bipartite Graphs
摘要
Abstract
The gracefulness of graphs which having widely applications is an important property of graphs. Makejie guessed that the coronal I(Km,n) of any complete bipartite graph Km,n is a K-graceful graph,where m,n,k are any positive integers and m ≤ n. In this paper, we proof the coronal I(Km,n ) of any complete 2 bipartite graph Km,n is a K-graceful Graph when m ≥6,n ≥(m^2-3m+2)/2 m〈n and m,n,k are any positive integers. Furthermore,the coronal I(Km,n ) of any complete bipartite graph Km,n is not K-graceful graph. The result enriches the graceful theory of graphs.关键词
