摘要
设G是一个简单图,若图G的一个k-正常边染色f满足对任意的uv∈E(G),都有C(u)≠C(v),则称f为G的一个邻强边染色,简称k-ASEC,并称x_(as)′(G)=min{k|G存在k-ASEC},为G的邻强边色数.其中C(u)={f(uv)|uv∈E(G)}.该文研究了一类正则极大平面图的邻强边染色,给出了着色方案,求解出其邻强边色数.
Let G(V,E) be a simple graph.A k -proper edge coloring f is called a k -adjacent strong coloring of G(V,E).iff every uv∈E(G) satisfies C(u)≠C(v),where C(u) = {f(u,v)|uv∈E(G)} is called k -ASEC for short and x(?)'(G) = min{k| There exist a k-ASEC of G} is called the adjacent strong edge chromatic number of G.In this paper we study the adjacent strong edge coloring of regular maximal plan graphs.And chromatic number and a kind of coloring of these graphs are solved.
