本文研究了圈的广义冠图CmFn,CmWn,CmCn的2-强边染色(D(2)-点可区别边染色).利用穷染、递推的方法得到了CmFn,CmWn,CmCn的2-强边色数(D(2)-点可区别边色数),并给出一种染色方案,推广了参考文献[6,7]的相应结果.
In this paper,the 2-strong edge coloring (D(2)-vertex-distinguishing edge coloring) of C m F n,C m W n,C m C n are studied.By using color one by one and recursion,2-strong edge chromatic number (D(2) vertex-distinguishing edge chromatic number) of them are obtained,the coloring method of the general crown graph of circle is given,which extends some corresponding results in [6,7].
