摘要
引入了图的D(β)-点可区别一般边染色,并对β=2的情形做了讨论,得到了路,圈,星,双星,扇,轮的D(2)-点可区别一般边色数,对于2距离色数等于3及4的图的D(2)-点可区别一般边色数做了探讨,特别研究了具有稳定2距离4着色的图的D(2)-点可区别一般边染色.文中提出了一个相关猜想和一个公开问题.
The concept of D(β)-vertex distinguishing general edge coloring is introduced and the case whenβ= 2 is discussed.D(2)-vertex distinguishing general edge chromatic numbers of path, cycle,star,double star,fan and wheel are obtained and the D(2)-vertex distinguishing general edge chromatic numbers of graphs with 2-distance chromatic number 3 or 4 are investigated in this paper. The D(2)-vertex distinguishing general edge colorings of graphs with stable 2-distance 4-colorings are studied.One conjecture and one open problem are proposed in this paper.
