摘要:

研究n阶完全图Kn(n≥20, n≡0(mod2))去掉4条独立边后的点可区别边染色, 并给出了图Kn-{v1v2,v3v4,v5v6,v7v8}(n≥20, n≡0(mod2))的点可区别边色数.

关键词: 边染色; 点可区别边染色; 点可区别边色数

Abstract:

We studied the vertex distinguishing edge coloring of Kn(n≥20, n≡0(mod2)) graph with four independent edges deleted, and obtained the vertexdistinguishing edge chromatic number of Kn-{v1v2,v3v4,v5v6,v7v8}(n≥20, n≡0(mod2)), where Kn-{v1v2,v3v4,v5v6,v7v8} is denoted by the complete graph with order n deleted edges {v1v2,v3v4,v5v6,v7v8} of Kn.

Key words: edge coloring, vertexdistinguishing edge coloring, vertexdistinguishing edge chromatic number
