摘要
研究立方Halin图以及一些倍图的均匀边染色,利用换色法、构造法和归纳法得出:立方Halin图和路的倍图都是均匀的,星的倍图都有均匀4边染色.
The equitable, edge-coloring of cubic Halin graphs and some double graphs are studied by using induction, interchange colors method and construction. The results indicate that cubic Halin graphs and the double graphs of path are equitable, and the double graphs of star have an equitable edge-coloring with 4 colors.
