摘要
根据3-正则Halin图的Hamilton性,结合其边的相邻关系,通过适当地选取边进行着色后证明了4和6阶以上3-正则Halin图G的边可区别数分别为3和2.
According to the Hamilton property of the 3-regular graph,and combining with the adjacent relations of the edges,proven that the edge distinguishing number of 3-regular graphG is respectively 3 and 2 on 4 and above 6 vertices by selecting edges properly and coloring.
