摘    要:设G(V,E)是一个简单图,k是一个正整数,f是一个V(G)∪E(G)到{1,2,…,k].的映射.如果Au,v∈E(G),则f(u)≠f(v),f(u)≠f(uv),f(v)≠f(uv),C(u)≠C(v),其中C(u)={f(u))U{f(uv)|uv∈E(G)).称f是图G的邻点可区别E-全染色,称最小的数k为图G的邻点可区别B全色数.本文给出了星、路、圈间的多重联图的邻点可区别E-全色数.

关 键 词:      重联图  邻点可区别E-全色数

Abstract:Let G(V, E) be a simple graph, k be a positive integer, f be a mapping from V(G) U E(G) to {1,2,... ,k}. If Auv ∈ E(G), we have f(u) ≠ f(v),f(u) ≠f(uv),f(v) ≠ f(uv),C(u) ≠ C(v), where C(u) = {f(u)} ∪ {f(uv)iuv ∈ E(G)}. Then f is called the adjacent vertex-distinguishing E-total coloring. The minimal number of k is called the adjacent vertex-distinguishing E-total chromatic number of G. The adjacent vertex-distinguishing E-total chromatic number of the multiple join graph of star, path and circle are obtained in this paper.
Keywords:Star  Path  Circle  the multiple join graph  adjacent vertex-distinguishing E-total chromatic numbe
